Title (EN) EXPRESSION EVALUATION OF DATABASE STATEMENTS FOR RESTRICTED DATA
(FR) ÉVALUATION D'EXPRESSION D'INSTRUCTIONS DE BASE DE DONNÉES POUR DES DONNÉES RESTREINTES
Abstract:
(EN) Computer systems, devices, and associated methods of evaluating an expression comprising restricted data are disclosed herein. In one embodiment, a method includes receiving a database statement from a client application and verifying the authenticity of the database statement. If the database statement is authentic, an approved expression is identified in the database statement for creating an evaluation rule. The method further includes restricting evaluation of expressions in a protected computing environment according to the created evaluation rule.
(FR) L'invention concerne des systèmes informatiques, des dispositifs et des procédés associés d'évaluation d'une expression comprenant des données restreintes. Dans un mode de réalisation, un procédé consiste à recevoir une instruction de base de données provenant d'une application client et à vérifier l'authenticité de l'instruction de base de données. Si l'instruction de base de données est authentique, une expression approuvée est identifiée dans l'instruction de base de données pour créer une règle d'évaluation. Le procédé consiste en outre à restreindre l'évaluation d'expressions dans un environnement informatique protégé, en fonction de la règle d'évaluation créée.
