Abstract: The HIP creation technique described herein pertains to a technique for creating a human interactive proof (HIP) by applying tearing and/or a conformal transformation to a string of characters while maintaining readability of text. In one embodiment, the technique tears a character string into two or more pieces and applies conformal transformation to warp the pieces in order to create a HIP. The transformation changes the shape and orientation of the characters but preserves angles of the characters which makes it easy for humans to recognize the characters after the transformation. Other embodiments of the technique create HIPs by applying tearing only to a string of characters, or by applying conformal transformation only to the character string.

Abstract: A security-enhanced login technique that provides a convenient and easy-to-use two factor technique to enhance the security of passwords without requiring any changes on the server side of a client-server network. The technique employs a convenient and easy-to-use two-factor technique to generate strong passwords for Web and other applications. In this technique, a convenient or personal device such as a mouse is used as the other factor besides a user password. A secret stored in the mouse or other personal device is hashed together with the password entered by a user and the server ID, to generate a strong, server-specific password which is used to authenticate the user to the server. This password enhancement operation is carried out inside the personal device.

Abstract: A “proxy re-signature system” provides various techniques for transforming a delegatee's signature on a message m into a delegator's on the same message m. Various embodiments of non-interactive re-signature generation processes are described. Various embodiments to aggregate part of signatures to reduce the size of re-signed signatures are also described. Various combinations of the proxy re-signature process and the re-signature conversion process result in an overall process that is unidirectional, multi-use, private, and non-interactive. As such, the proxy re-signature system is applicable for use with a wide range of applications.

Abstract: A “Performance Evaluator” provides various techniques for tracking system events to diagnose root causes of application performance anomalies. In general, traces of system events involved in inter-thread interactions are collected at application runtime. These traces are then used to construct inter-thread dependency patterns termed “control patterns.” Control patterns are then evaluated to determine root causes of performance anomalies. Where an application terminates abnormally or full traces cannot be collected for some reason, partial control patterns are constructed for that application. In various embodiments, “fingerprints” are then generated from full or partial control patterns and are matched to fingerprints corresponding to operations in other control patterns extracted from reference traces collected on the same or similar systems. Matched fingerprints or control patterns are then used to deduce the root cause of application performance anomalies associated with full or partial traces.
