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 authentication method is disclosed. To authenticate a user, a mobile device may request identification and verification from the user. Upon receiving a positive identification and verification response from the user, the mobile device may generate a cryptogram using a user identification (ID) associated with the user, a timestamp, a device ID associated with the mobile device, a service provider application ID associated with the service provider application, and a service provider device ID. The mobile device may transmit the generated cryptogram, the user ID, the timestamp, the device ID, the service provider application ID, and the service provider device ID, to a service provider computer associated with the service provider application. The service provider computer may decrypt the cryptogram and compare the decrypted data elements to the received data elements to validate and authenticate the user.
