i have noticed a lot of confusion about size and resolution of digital images. i' ll try to provide some clarification here. note that this discussion applies only to bitmapped digital images, which are the kind you are dealing with when you use a scanner or digital camera. vector images are another matter but they are not relevant in this context .
first of all you need to realize that a digital image really does not have a physical size. to say that a digital image is, say, 4x6 inches is meaningless. after all, the image is just a collection of pixels stored in memory or on your hard disk. a digital image does, however, have a pixel size - the number of pixels horizontally and vertically. this is the only
size
that is inherent in any bitmapped digital image .
one system that has attempted to address these issues is provided through the use of digital postmarks, digital postmarks are intended for use in an enterprise environment, and are designed to specifically provide authentication of message contents. fundamentally it is designed as a non - repudiation service. fig. 3 illustrates an exemplary installation of a system to use digital postmarking. user a 100 uses a client to generate an email message. this message is sent from a client to an outgoing mail server 130, typically provided by an enterprise associated with user a 100, outgoing mail server 130 receives the message and forwards it to the digital postmarking server 132. server 130 preferably signs the message prior to transmission to digital postmarking server 132 so that postmarking server 132 can verify that the message was not altered in transit. digital postmarking server 132 then validates the authenticity of the signature against a known key associated with either user a 100 or with mail server 130. upon successful verification, the digital postmarking server 132 generates a timestamp that, along with the message, the signature and validation results are stored in a digital postmark non - repudiation database 134. this information can then be accessed at a later date to establish a non - repudiation function. the postmarks server 132 and database 134 generate a digital postmarking receipt that is transmitted back to the outgoing mail server 130. the outgoing mail server 130 wraps the original message in the digital postmarking receipt and transmits the message to the incoming mail server 136. user b 112 retrieves the message in the proprietary digital postmarking wrapper 138 using a proprietary client 140. the client 140 can then retrieve the authentication information from the digital postmark non - repudiation database 134. client 140 does not need to perform any verification processes on the message itself, as the verification, receipt and even the original document can be retrieved from database 134, alternately a local cryptographic verification can be performed by client 140 .

wow, the thread is alive, i like that keijo - thank you for providing your insight as always, especially valuable with your relevant professional backround! dcstamp - perfect! that' s absolutely some heavy arguments for me to stick with powerpoint, first of all because i am no data - geek at all. i would love to have this detailed set of instructions! floortrader - i understand your concern, no doubt it would be easy for anyone to' fake' a digital collection if that would give them any pleasure. if anyone would happen to look at any off my digital stuff and think it' s not right, so be it, i would still keep my own pleasure in doing it. don - your album is beautiful, love the flip - over presentation of your stuff. however i think your missing the concept, as your' digital album' presents images of your actual hard - copy album pages (as far as i understand anyway ?) the topic of this thread was more like creating digital album pages from scratch, only presenting the images of the actual stamps themselves. that would enable editing of your digital album any way you like, while your stamps would simply stay put wherever it is stored. like in your admirable album... thank you all for valuable inputs to the discussion! before i conclude to stick with powerpoint... . as i am quite lazy by nature, i have considered using the steiner pages as a starting point, and then develop them further for my digital collection. that would save me an immense job in creating frames, adding data etc... does anybody know if it is possible to insert images, textboxes, frames etc on the editable steiner pages ?
although the digital postmarking, system discussed with relation to fig. 3 can provide both authentication of a sender and the message, it requires proprietary software, and is cumbersome. the system is designed for implementation in an enterprise environment, and does not take into account the needs of individuals. the digital postmarking server 132 is often dedicated to a particular outgoing mail server 130. as such digital postmarking server 132 requires that the enterprise obtain a dedicated hardware device and implement a complex process of having either client software sign a message or having the mail server 130 sign message prior to beginning the verification process. the storage requirements for database 134 can be immense if all messages and attachments are stored for a number of different organizations. as such, the verification information is typically only stored for a predefined period. if this period expires, the ability to authenticate the message can be adversely affected .
[ 004 ] the present invention provides an archive system that customers may access through a browser over a network using secure communication transmissions, and using electronic postmarks (
epms
) to facilitate tracking of customer data. an epm is a time - stamped and cryptographically sealed digital hash that accompanies an electronic message, to detect modification of the latter. the epm for a message may include a time and date stamp indicating when the epm was generated. the contents of an epm are digitally
sealed
by the addition of a digital signature. an exemplary epm is described in u. s. serial no. 09 / 675, 677, filed september 29, 2000, by leo j. campbell et al. and titled
systems and methods for authenticating an electronic message ,
the disclosure of which is expressly incorporated herein by reference to its entirety. in addition, an embodiment of the invention provides an archive system that is independent of customer hardware and software platforms .
cryptographic mechanisms or cryptographic arrangements for secret or secure communication including means for verifying the identity or authority of a user of the system or for message authentication, e. g. authorization, entity authentication, data integrity or data verification, non - repudiation, key authentication or verification of credentials involving digital signatures
[ 034 ] as shown in figure 5, a customer 120 may submit to the archive system 101 over network 110 a link request to permit a third party to access an archived electronic file to which customer 120 has access (stage 510). the link request may include information identifying the archived electronic file, customer identification information, such as a digital certificate and optionally a name and password, and a third party' s digital certificate. the information identifying the archived electronic file may include, for example, a filename for the electronic file. archive administrator component 275 creates a link request epm and applies it to the link request by generating a record for the transaction in transaction log 265 in archive database 260 (stage 515). a link request epm may include the time and date of the link request, the information identifying the archived electronic file, the customer identification information, and information about the third party' s digital certificate .

it can be useful, however, to assign a physical size to a digital image. suppose that you scan a 4x6 inch postcard. if the resulting image is assigned the size
4x6 inches
then people viewing the image will know the actual size of the postcard. it also means that when you print the image at
normal
size it will print at this size (at least with all the software i have seen). all digital image files include this size information with an image. scanned images are assigned a physical size that corresponds to the actual size of the area that is scanned - which makes perfect sense .
the epm technology complies with standards set forth in the u. s. electronic signatures in global and national commerce act of 2000, which gave legal status to digital signatures. however, without a case to test the validity of the technology, there is no way to know whether courts will accept epms, chamberlain said .
[ 003 ] current electronic archive systems provide for the long - term storage of electronic files. typically such systems require specialized software and / or are incorporated in document management software packages, such as docuxplorer by archive power systems, inc. one known system for providing archival and retrieval of electronic messages, such as emails and their attachments, is zantaz, by zantaz, inc. what is needed is a secure archive system for archival and retrieval of customer data files by incorporating secure customer identification through the use of digital certificates, and by utilizing electronic postmarks (
epms
) to store customer data and to facilitate tracking of customer data. what is also needed is a secure archive system that is independent of customer hardware and software platforms .
then there' s the matter of resolution, which is usually expressed in terms of pixels per inch (ppi, sometimes referred to as dots per inch or dpi). perhaps you have already realized that once a digital image is assigned a size it automatically has a resolution. here' s the formula for horizontal resolution :
the epm technology complies with standards set in the u. s. electronic signatures in global and national commerce (e - sign) act of 2000, which gave legal status to digital signatures. however, without a case to test the validity of the technology, there is no way to know whether courts will accept epms, chamberlain says .
interesting concept, i can see it being used by a person writing a article or a researcher using it for education. but i fought against people who claim ownership of material when in fact they just stole a picture from a stamp auction off the internet. so i have a hard time accepting these digital albums after spending a life time building my collection. many times i have shown some pages and the stamps would catalog a few dollars and someone who never shows their stuff on a regular basis throws up a scan of a $ 5, 000 or $ 10, 000 stamp, then say it is from their collection. that kind of diminishs my page. so no i have a negative respond to digital albums .

pictures of the letters seen by the guardian show many of them featured the same pseudonym or initials. three of the letters received by us mosques were sent at the same time, with the postmarks reading 5. 14pm or 5. 15pm on 22 february. “there were two second - class stamps on all the letters sent to the us, which is interesting, ” said steve rose, who is responsible for content at faith matters, a community action group working to counter extremism .
clicking the apply epm button will launch a step - by - step process for locking the document' s content, signing it with the user' s digital certificate and placing a record of the signed document in the usps epm repository. once the document has been signed, a usps epm logo will be affixed to the document, indicating that it has been signed and the content is valid .
i love this subject, and i love it when others show off there digital albums. while i have been developing digital albums for several years now at dcstamps, in actuality, i got the original idea from kcb' s blog (kiitos keijo). i also love it when others show their work so i really appreciate seeing the pages from blaamand. for those skeptic out there, yes it is a lot of work scanning your stamps, but it is really the only way of effectively showing off your collection to many people around the world. also, it allows you to display your collection exactly in the manner you want - highlighting the important aspects in a way that no preprinted pages can. what makes it even better, is that you can easily change your pages to include new items or changes in your collection .
sometimes there is not a problem reading a postmark, but rather you want to
lift
the postmark to make a clean copy of it - in other words, an image of the postmark without the stamp. this is sometimes needed for overprints, surcharges, and the like as well as for postmarks. the technique described here can also be used in some situations for reading a difficult postmark. this technique works best if the postmark or overprint is black and the rest of the stamp is colored with no black elements in the design .
one skilled in the art will appreciate that though there are many systems for providing digital signatures on email messages to allow for verification of the integrity of the message body, they all introduce a number of different layers of complexity. addition of authenticated time stamping functionality is difficult to provide without the addition of additional server side hardware, much as the ability to authenticate the sender of a message requires the cumbersome management of encryption keys .
in some areas of philately, watermarks are very important and can make the difference between a $ 2 stamp and a $ 2000 stamp. the ability to create digital scans of stamps that show the watermark will be useful to many philatelists. i have devised a technique that can be used to create such scans. it can be used only with a flat - bed scanner, and may not work well with the less easily seen watermarks .
[ 027 ] as shown in figure 3a, archive administrator component 275 creates the storage epm 370 by generating a hash file 374 from the electronic file 372, and storing the hash file 374 in storage epm 370 (stage 340). archive administrator component 275 may generate hash file 374 using known hashing techniques, such as a secure hash algorithm (
sha - 1), a technique based on an algorithm provided by rivest, shamir, and adelman (
rsa
), and a message digest algorithm (
md5
). archive administrator component 275 also stores in storage epm 370 a time and date stamp 375 to indicate the time and date of the storage of the electronic file. in addition, archive administrator component 275 may store in storage epm 370 a digital signature 376 having a digital key 377 for digitally securing the storage epm 370. further, archive administrator component 275 may store customer identification information in storage epm 370 .
in an embodiment of the first aspect of the present invention, the step of processing the message includes determining the digital signature by encrypting a cryptographic hash of the electronic message, possibly just the body of the electronic message, using the private portion of a private - public key pair. in another embodiment, the step of processing the electronic message can include overwriting header values such as time and date values in using verified header values (e. g. verified time and date values) .
very nice tool and collection. works really well if you have your stamps in an album. for those of us making digital albums, i think we like designing them around our specific collection and being able to put what information we actually want on it. as for me, i collect dead countries, no one has designed album pages with such a specialty, so i resorted to designing my own. here is an example of a couple of my pages that i made to fit my specific collection :
i think the notion of a digital album is a great idea. i' ve thought about doing something like that, although since i don' t store my stamps in albums per se, preferring stockbooks or cards, depending on the area, i prefer to just use a general gallery approach to my online presentations. many of you have seen my main website: urltoken i also have a few other fledgling websites devoted to other philatelic topics: urltoken urltoken each one is slightly different in terms of presentation .
here is a colorful, annotated series of powerpoint slides prepared (and recently updated as of 20 may 2018) by greg bondar. greg prepared these from research of tei coding, our photos of letters from the reading central library (posted with their permission), and information from the canonical reference tome, alcock and holland’s the postmarks of great britain and ireland. (note that the online version of this is not complete, and we have the hardbound version to consult within the mitford project .) greg designed this series of slides to help us with identifying and encoding some of the more challenging aspects of 19th - century mansucript letters! thanks, greg!
a digital postmark ( dpm ) is a technology that applies a trusted time stamps issued by a postal operator to an electronic document , validates electronic signatures , and stores and archives all non-repudiation data needed to support a potential court challenge - it guarantees the certainty of date and time of the postmarking . this global standard was renamed the electronic postal certification mark ( epcm ) in 2007 shortly after a new iteration of the technology was developed by microsoft and poste italiane . the key addition to the traditional postmarking technology was integrity of the electronically postmarked item , meaning any kind of falsification and tampering will be easily and definitely detected . additionally , content confidentiality is guaranteed since document certification is carried out without access or reading by the postal operator . the epcm will eventually be available through the upu to all international postal operators in the 191 member countries willing to be compliant with this standard , thus granting interoperability in certified communications between postal operators . in the united states , the us postal service operates a non-global standard called the electronic postmark , although it is soon expected to provide services utilizing the epcm .
