摘要:
Compliance of a project is assessed by generating a graph including nodes representing attributes of the project, and populating a subset of nodes in the graph with attribute values of the project. A rule applicable to the subset of nodes is identified and applied to determine whether the attribute values comply with the rule.

A questionnaire generation process presents a first subset from a set of questions of the questionnaire and receives first answers from a user. The first answers are used to determine whether the first answers are sufficient to give definite values to conditions of first rules, wherein the first rules have conditions for providing output. When the first answers are not sufficient, the conditions of the first rules can be used to identify a second subset of the questions, wherein the second subset of questions has second answers such that a combination of the first and second answers is sufficient to give definite values to the respective conditions of the first rules, and the second subset of questions can be presented to the user.

摘要:
A method of establishing a secure channel between a human user and a computer application is described. A secret unique identifier (“PIN”) is shared between a user and an application. When the user makes a request that involves utilizing the PIN for authentication purposes, the application renders a randomly selected identifier. The randomly selected identifier is in a format that is recognizable to a human but is not readily recognizable by an automated agent. The randomly selected identifier is then presented to the human user. The user identifies the relationship between the randomly selected identifier and the PIN. If the user's input reflects the fact that the user knows the PIN, then the user is authenticated.

Systems and methods are provided for authentication by combining a Reverse Turing Test (RTT) with password-based user authentication protocols to provide improved resistance to brute force attacks. In accordance with one embodiment of the invention, a method is provided for user authentication, the method including receiving a username/password pair associated with a user; requesting one or more responses to a first Reverse Turing Test (RTT); and granting access to the user if a valid response to the first RTT is received and the username/password pair is valid.

A process includes analyzing events reported by computing devices on a network to recognize patterns of events that occurred on the network and sharing with a community, information concerning the patterns detected. The process may also use consolidated information on the patterns to select one or more of the patterns for analysis that identifies whether the selected patterns result from malicious activity. The consolidated information includes information on the patterns detected on the network and information concerning corresponding patterns of events that occurred elsewhere.

Systems and methods are provided for performing transactions and managing communications using a trusted third party. In one embodiment, a sender transfers an encrypted version of a file (such as a digitally encoded audio track, movie, document, or the like) to someone who wishes to receive it. The receiver computes a first hash of at least a portion of the encrypted data content, and sends the first hash to a third party configured to compare at least a portion of the first hash to at least a portion of a second hash. The receiver receives a file decryption key from the third party, and decrypts at least the portion of the received encrypted data content with the decryption key. In some cases, multiple hashes of the encrypted data content may be computed, each using a different portion of the encrypted data content.
