摘要： A system and associated protocols for communication between two entities across a computer network operate such that the identities of the two entities remain concealed from each other, while ensuring that no third party is able to trace the existence of a conversation between them. The two entities correspond to each other through pseudonyms. The protocols are designed with an object to distribute trust so that an identity is not revealed by the compromise of any one agent involved in the execution of the protocol. No one agent can establish a correlation between a pseudonym and a physical address.

摘要： The present invention relates to a method, system and computer program product for enabling the remote authentication of fingerprints over an insecure network using a client-server architecture by generation of a set of random queries relating to fingerprint patterns based on stored fingerprint data at the server, to which the client responds based on the observed fingerprint patterns, followed by the issuing of a randomly generates set of challenges pertaining to geometrical relationships between the fingerprint patterns for which confirm responses are received by their server, the final authentication being determined by the proportion of correct responses by the client to said challenges.

摘要： A solution to the general problem of Secure Storage and Retrieval of Information (SSRI) guarantees that also the process of storing the information is correct even when some processors fail. A user interacts with the storage system by depositing a file and receiving a proof that the deposit was correctly executed. The user interacts with a single distinguished processor called the gateway. The mechanism enables storage in the presence of both inactive and maliciously active faults, while maintaining (asymptotical) space optimailty. This mechanism is enhanced with the added requirement of confidentiality of information; i.e., that a collusion of processors should not be able to learn anything about the information. Also, in this case space optimality is preserved.
摘要翻译：安全存储和信息检索（SSRI）的一般问题的解决方案保证即使某些处理器出现故障，存储信息的过程也是正确的。用户通过存放文件和接收证明表明存款被正确执行，与存储系统进行交互。用户与称为网关的单个不同的处理器进行交互。在保持（渐近）空间优化的同时，该机制可以在存在无效和恶意活动故障的情况下进行存储。随着信息机密性的增加，这种机制得到加强; 即处理器串通不应该能够了解有关信息的任何内容。此外，在这种情况下，空间最优性得以保留。
