Abstract: Devices and techniques for controlling disclosure of sensitive information are provided. A request for information may be received through a first communication channel. The request may be provided using an account of a user. First encrypted data, which includes the requested information and has been encrypted with a first asymmetric encryption key, may be decrypted. The decrypted information may be re-encrypted with a second asymmetric encryption key different from the first asymmetric encryption key to obtain second encrypted data comprising the information. The second encrypted data may be sent to the user through a second communication channel different from the first communication channel.
