User policy for trusting web sites

A system for trusting sites in a communication network, the communication network including a plurality of user nodes inter-linked through at least one proxy node to at least one site server, the system comprising:

• at least one user accessing from a user node, through a proxy node to a server site;
• the server site providing to said proxy node, through said communication network, at least one input credential;
• the proxy node feeding said at least one input credential to an advanced policy to deduce a plurality of verified general-context declarations related to said site in addition to the authentication said site, wherein if said plurality of declarations cannot be deduced, the proxy node receiving at least one additional input credential and feeding said at least one additional input credential to said advanced policy until a plurality of verified general-context declarations related to said site in addition to the authentication of said site are deduced;
• the proxy node associating a symbol with each one of said plurality of verified general-context declarations;
• and
• the proxy node sending the symbol to the user node and the user displaying said symbol in a predefined way that cannot be set by said site,
• wherein said advanced policy is deducing said plurality of verified general-context declarations as a function of at least one existing credential known to said advanced policy, or to said input credential or said at least one additional input credential.

A computer software product, including a computer-readable medium in which computer program instructions are stored, which instructions, when read by a computer, cause the computer to perform a method for trusting sites in a communication network, comprising:

• receiving at least one input credential to authenticate a site;
• feeding said at least one input credential to an advanced policy to deduce a plurality of verified general-context declarations related to said site in addition to the authentication of said site, wherein if said plurality of verified general-context declarations cannot be deduced,
• receiving at least one additional input credential, and feeding said at least one additional input credential to said advanced policy to deduce a plurality of verified general-context declarations related to said site in addition to the authentication of said site, until a plurality of verified general-context declarations related to said site in addition to the authentication of said site are deduced;
• associating a symbol with each one of said plurality of verified declarations;
• and
• displaying said symbol in a predefined way that cannot be set by said site,
• wherein said advanced policy is deducing said plurality of verified general-context declarations as a function of at least one existing credential known to said advanced policy, or to said input credential or said at least one additional input credential.
