Techniques for obfuscating and deploying digital assets (e.g., mobile applications) are provided to mitigate the risk of unauthorized disclosure. An asset can be received that is to be deployed to a plurality of mobile devices, each of the mobile devices associated with a corresponding account having account attributes. A deployment group of one or more mobile devices for deploying the asset can be identified based on a set of one or more obfuscation parameters, comprising account attributes shared among the one or more mobile devices within the deployment group. A customized obfuscation scheme to be applied to the asset can be determined based at least in part on the set of obfuscation parameters. The customized obfuscation scheme can be applied to the asset to generate an obfuscated asset. The obfuscated asset can be transmitted and/or updated over a network to the one or more mobile devices within the deployment group.

Methods and systems for asset obfuscation

An encrypted table value homomorphically joining method and apparatus comprising receiving a query input. Based on the query input, the method may include determining at least one field on which to join the plurality of tables, and determining that the at least one field contains deterministically homomorphically encrypted data. The method may include determining a homomorphic join strategy directly comparing values in two homomorphically encrypted fields, performing a homomorphic join on the fields in the plurality of tables, and providing resultant homomorphically joined tables.

Homomorphic database operations apparatuses, methods and systems

The HOMOMORPHIC DATABASE OPERATIONS APPARATUSES, METHODS AND SYSTEMS ('HEDO') transform transaction storage requests and homomorphic model queries using HEDO components into homomorphic model query results. In some implementations, the disclosure provides a processor-implemented method of securely querying a shared homomorphically encrypted data repository and performing cross-table homomorphic joins.
