  • Patent number: 7421733
    Abstract: When a user successfully logs into an account, the user is provided with a first-class login token, which entitles the user to one or more unsuccessful login attempts without experiencing delays the user would otherwise experience. If attempts with a second-class login token or an expired first-class login token is impermissible, a subsequent login attempt is subject to delays the user would otherwise not experience. The delays minimize the effectiveness of dictionary attacks. Additionally, if the user attempts to login without a login token or an invalid login token, the login attempt is impermissible and the user is provided with a second-class login token for use in a delayed, subsequent login attempt.

  • Publication number: 20080133536
    Abstract: The present invention extends to methods, systems, and computer program products for scalable differential compression for network data. Network data exchanged between Wide Area Network (“WAN”) acceleration devices is cached at physical recordable-type computer-readable media having (potentially significantly) larger storage capacities than available system memory. The cached network data is indexed through features taken from a subset of the cached data (e.g., per segment) to reduce overhead associated with searching for cached network data to use for subsequent compression. When a feature match is detected between received and cached network data, the cached network data can be loaded from the physical recordable-type computer-readable media into system memory to facilitate data compression between Wide Area Network (“WAN”) acceleration devices more efficiently.

  • Patent number: 7149801
    Abstract: A resource may be abused if its users incur little or no cost. For example, e-mail abuse is rampant because sending an e-mail has negligible cost for the sender. Such abuse may be discouraged by introducing an artificial cost in the form of a moderately expensive computation. Thus, the sender of an e-mail might be required to pay by computing for a few seconds before the e-mail is accepted. Unfortunately, because of sharp disparities across computer systems, this approach may be ineffective against malicious users with high-end systems, prohibitively slow for legitimate users with low-end systems, or both. Starting from this observation, we identify moderately hard, memory bound functions that most recent computer systems will evaluate at about the same speed, and we explain how to use them for protecting against abuses.

  • Publication number: 20040117718
    Abstract: Systems and methods for constructing Reed-Solomon encoding matrices are provided that are simpler and more regular than existing techniques, and which allow for the coding to be applied to more data disks than previous techniques. More particularly, systems and methods for simplifying the construction of Reed-Solomon based erasure codes, or coding matrices, over GF(2{circumflex over ( )}n) in connection with circumstances wherein the number of errors to be corrected is less than or equal to three are provided.

  • Patent number: 6269362
    Abstract: Provided is a computerized method for monitoring the content of documents. A set of documents is stored in memories of server computers. The server computers can be connected to each other by a network such as the Internet. Entries are generated in a search engine for each document of the set. The search engine is also connected to the Internet. The entries are in the form of a full word index of the set of documents. The search engine also maintains a first abstract for each document that is indexed. The abstract is highly dependent on the content of each document. For example, the abstract is in the form of a sketch or a feature vector. Periodically a query is submitted to the search engine. The query locates a result set of documents that satisfy the query. A second abstract is generated for each document member of the result set. The first and second abstracts are compared to identify documents that have changed between the time the set of documents were indexed and the time the result set is generated.
