US Patent 9923719 Location aware cryptography

Encrypted data transmitted from a second entity to a first entity may be received. The encrypted data may be encrypted by a location based public key based on a public key and a location associated with the second entity. A location associated with the first entity may be identified. A location based private key may be generated based on a private key that corresponds to the public key and the location associated with the first entity. Furthermore, the encrypted data may be decrypted with the location based private key when the location associated with the first entity matches the location associated with the second entity.
