Described are examples for securely storing stream data received from a stream source. Stream data can be received from the stream source for storing in one or more secured buffers of a secure memory, wherein the stream data includes a header portion generated by a driver for the stream source and a payload portion generated from the stream source. The payload portion of the stream data can be stored in the one or more secured buffers and contiguous to a previous payload portion of previous stream data received from the stream source. The header portion of the stream data can be stored in another portion of the secure memory or a non-secure memory. A data frame, from the one or more secured buffers, comprising at least the payload portion of the stream data and the previous payload portion of the previous stream data can be provided to an application.
