What is it called when an individual's confidential information is viewed by an unauthorized person?

The term used when an individual's confidential information is viewed by an unauthorized person is known as "an inadvertent disclosure." This refers to instances where data is exposed unintentionally due to carelessness, a security breach, or a failure in protocol. Such disclosures can significantly undermine the trust individuals have in the systems designed to protect their sensitive information.

Inadvertent disclosures typically occur without malicious intent, distinguishing them from other forms of data breaches. Secure handling of confidential information often includes protocols and safeguards to minimize the risk of inadvertent disclosures.

The other potential answers do not accurately reflect the nature of unauthorized viewing of confidential information. For example, "private release disclosure" and "agreed disclosure" suggest that there was some level of authorization or consent involved, which contradicts the fundamental aspect of unauthorized access. "Consented disclosure" indicates that an individual has authorized their information to be shared with others, which is the opposite of what occurs in cases of unauthorized access. Thus, "an inadvertent disclosure" precisely captures the situation described in the question.
