....Would another certificate have to be issued for a book, whose certificate is no longer valid And if certificate re issue was chosen, what would the effects be on the system Given these questions, a decision was made to use the catalogue hashes as the primary trust mechanism. Anderson et al. [85] defined a mechanism to incorporate this catalogue based trust into the World Wide Web framework, by defining special HTML tags. 7.2 Information Retrieval Systems From sections 6.2 and 6.4, we can see that attempts have been made to perform trust management in this domain. The primary trust ....

....requires clarification. This question more specifically asks Will I get an authentic copy of the information that I requested and Will I get only the information I requested Many solutions to the former question have been created, using public key cryptography. However, we see the WAX system [85] taking a different approach and using hashes instead. The latter question is a much more difficult question to answer and we have not come across any solutions. The question of the effects that information will have on one s system relates directly to active content. Mechanisms exist to minimise ....

....with various rights in a common manner. This system enables service providers to reduce the development costs of the ticketing software hardware and also enables users to view and manage various tickets using a common ticket wallet , which greatly improves usability. The trust management scheme [1][3] 6] 7] developed for digital certificates and the double spending protection scheme [2] 14] developed for digital cash can also be applied to digital tickets as base technologies, since digital tickets have aspects of both digital certificates and digital cash. These technologies, however, do ....

....in which the transferor loses the rights when the certificate is transferred. As a result, it is difficult to realize event tickets or other tickets that can be consumed only once, although we note that it can be applied to license or pass type tickets. The Eternal Resource Locator [1] presents a scheme to establish trust without relying on any PKI. This scheme uses the hash value of the root hypertext document as the basis of trust. Our scheme has similarities to this in that the hash value of the type definition is used as the basis of trust. NetBill [6] presents an ....

....to a single signature on each new version of a publisher s catalogue. The Wax design has had some success in the UK medical informatics field. But it uses a proprietary hypertext format, so the next step was to generalise it to work with html. The result was the ERL, or eternal resource locator [3], which can be thought of as a URL plus a hash of what you expect to find there. Having developed this, we realised that it was very powerful and useful: the writer of a web page or other document can authenticate any digital object by simply including its ERL, and this enables the construction of ....

....next asked to look at an online medical application (the British National Formulary, which is the list of all drugs approved for prescription in the UK [2] the obvious step was to generalise our ideas to work with html. The result was the ERL, or eternal resource locator, which is described in [3]. An ERL is essentially a URL plus a hash of what one should expect to nd there. Thus a medical publisher can modify his online catalogue to replace the URLs of his online books with ERLs, and now users whose browers have a plugin which can parse and verify the hashes, get the same protection as ....
