Security and content protection by test environment analysis

A system, comprising:

• a candidate client device including:
• a processor configured to implement a candidate evaluation software application,
• a camera configured to record a sequence of images of an environment of the candidate client device, and
• a microphone configured to record audio data in the environment of the candidate client device;
• and
• one or more server hardware computing devices communicatively coupled to a network and in communication, via the network, with the candidate client device, and each comprising at least one processor executing specific computer-executable instructions within a memory that, when executed, cause the one or more server hardware computing devices to:
• receive the sequence of images and the audio data from the candidate client device,
• extract a first video attribute from the sequence of images,
• extract a first audio attribute from the audio data,
• determine that at least one of the first video attribute violates a first video condition and the first audio attribute violates a first audio condition, and
• prevent the candidate client device from performing a candidate evaluation function using the candidate evaluation software application.
