Which of the following statements best describes the difference between the role of a data owner and the role of a data custodian?
The security challenges for DRM are as follows:
Key hiding: It prevents tampering attacks that target the secret keys. In the key hiding process, secret keys are used for
authentication, encryption, and node-locking.
Device fingerprinting: It prevents fraud and provides secure authentication. Device fingerprinting includes the summary of hardware
and software characteristics in order to uniquely identify a device.
OTA provisioning: It provides end-to-end encryption or other secure ways for delivery of copyrighted software to mobile devices.
Answer B is incorrect. Access control is not a security challenge for DRM.
