  • Publication number: 20230125608
    Abstract: Disclosed herein are system, method, and computer program product embodiments for encrypting and decrypting a sensitive data item using a zero-knowledge encryption protocol. An embodiment operates by receiving a request to decrypt the sensitive data item from a client. The embodiment retrieves the requested sensitive data item from a data store. The embodiment generates a result set by replacing a ciphertext value of the sensitive data item to be stored in the result set with a placeholder identifier. The embodiment retrieves a data encryption key (DEK) block from a DEK manager, wherein the DEK block comprises a DEK associated with the sensitive data item. The embodiment generates and encrypts a cipher ticket comprising the ciphertext value of the sensitive data item. The embodiment then sends the result set, the cipher ticket, and the DEK block to the client for decryption of the ciphertext value of the sensitive data item.

  • Patent number: 10713246
    Abstract: A system, method, and computer-readable medium, to receive a query specifying a result set of data from at least one database table; determine whether at least one column of the at least one database table is subject to a column-based authorization restriction; modify the query, in an instance it is determined that at least one column of the at least one database table is subject to a column-based authorization restriction, to restrict the result set of data in accordance with the column-based authorization restriction; and execute, in response to the modifying of the query, the modified query.

  • Patent number: 9760734
    Abstract: Embodiments manage user authorization to access multiple grouped software applications, via a catalog mechanism. Functionality of related software is divided into semantically meaningful catalogs, representing tasks or sub-processes within a business scenario. These catalogs represent a unit of functionality utilized to structure work and authorization. Functionality and authorizations are associated to system entry points, and assigned to catalogs bundling applications and services. Responsibilities may be defined statically or dynamically in terms of rule-based access restrictions to data structure (e.g., business object) instances. Catalogs may be assigned to business roles, and business roles assigned to users. Based on such assignments, corresponding authorizations are generated and linked to users at compile or deployment time. At run time, access decision and enforcement is granted based on these authorizations and restrictions.

  • Publication number: 20140181134
    Abstract: A query engine for integrating authorization conditions within a database query statement. The query engine may include an authorization handler configured to receive authorization parameters related to one or more authorization objects for data relevant to a query for performing an authority check, and obtain at least one user authorization profile for a current user based on the authorization parameters. The at least one user authorization profile may include an activity value and one or more authorization conditions associated with the activity value. The query engine may further include a query generator configured to receive query parameters related to the query and integrate the query parameters with the one or more authorization conditions to obtain a database query statement, and a database selector configured to obtain authorized data from an in-memory database based on the database query statement.
