Monitoring for interception of image display pipeline and indicating to user

A method of display processing at a device, comprising:

• configuring, in a secure mode or a protected mode, one or more CRC registers for storing a first set of CRC values that correspond to at least one application;
• storing the first set of CRC values in the configured one or more CRC registers;
• receiving an indication that the at least one application is in an activated state as executed by a processor of an operating system (OS), wherein the indication is associated with a first set of cyclic redundancy check (CRC) values that correspond to the at least one application;
• generating, after storage of the first set of CRC values in the configured one or more CRC registers, a user interface (UI) indication for the at least one application based on the received indication that the at least one application is in the activated state;
• transmitting, based on the generated UI indication, at least one UI layer corresponding to the generated UI indication for the at least one application;
• and
• detecting a security breach of the at least one application based on a mismatch between a second set of CRC values determined based on the transmitted at least one UI layer and the configured one or more CRC registers that store the first set of CRC values in the secure mode or the protected mode.

A non-transitory computer-readable medium storing computer executable code, the code when executed by at least one processor, causes the at least one processor to:

• configure, in a secure mode or a protected mode, one or more CRC registers for storing a first set of CRC values that correspond to at least one application;
• store the first set of CRC values in the configured one or more CRC registers;
• receive an indication that the at least one application is in an activated state as executed by a processor of an operating system (OS), wherein the indication is associated with a first set of cyclic redundancy check (CRC) values that correspond to the at least one application;
• generate, after storage of the first set of CRC values in the configured one or more CRC registers, a user interface (UI) indication for the at least one application based on the received indication that the at least one application is in the activated state;
• transmit, based on the generated UI indication, at least one UI layer corresponding to the generated UI indication for the at least one application;
• and
• detect a security breach of the at least one application based on a mismatch between a second set of CRC values determined based on the transmitted at least one UI layer and the configured one or more CRC registers that store the first set of CRC values in the secure mode or the protected mode.
