  • Patent number: 10601593
    Abstract: A “Database Confidentiality System” provides various techniques for using server-side trusted computing in combination with configurable type metadata and user- or system-definable rules associated with individual database fields to implement database confidentiality. In various implementations, type metadata and one or more rules are added to each database field. Metadata includes a domain, method of encryption, and a pointer to an encryption key used to encrypt the data in the corresponding field. The rules define one or more operations allowed on the corresponding data types. The type metadata and rules are optionally integrity protected and/or encrypted to avoid unauthorized changes or access. Various encryption techniques (e.g., probabilistic, Paillier, etc.) allow some computations to be performed in an untrusted environment without access to the encryption key.

  • Patent number: 9262597
    Abstract: A request that includes an indication of an execution context and data that represents executable code is obtained. An analysis of the data is initiated based on generating a first templatized representation of the executable code. A list of clearance indicators that indicate a blocking status associated with respective forms of templatized representations is accessed. A workflow policy is determined based on the accessing of the list of clearance indicators. The list of clearance indicators is updated, based on a result of the analysis of the data.

  • Patent number: 8726254
    Abstract: Program source code is annotated to support dataflow analysis or other program analysis, without requiring changes to compilers. Annotation statements are embedded inside comments or other non-code-generative portions of the source code. The annotations can be used to express contracts at routine boundaries, allowing an analyzer to check the global correctness of the source code through modular (local) analysis, with performance that is linear in the number of routines. In particular, annotated SQL source code may be analyzed to identify SQL injection vulnerabilities.
