What is a method of disguising information so that it is unintelligible to unauthorized individuals?

The correct answer is the method of disguising information so that it is unintelligible to unauthorized individuals is scrambling. Scrambling involves altering the data in a manner that it becomes unreadable or indecipherable to anyone who does not possess the necessary means to revert it to its original form. This technique is often used in telecommunications and data transmissions to maintain the security and confidentiality of sensitive information.

Scrambling can take various forms, such as encryption, where data is transformed into a format that can only be understood by those who have the decryption key or algorithm. This practice is crucial in protecting intellectual property, personal data, and any information that necessitates confidentiality.

Other options, while related to data transmission and management, serve different roles in information processing. For example, interconnection decoy refers to creating fake or misleading connections to protect actual data paths, which does not inherently disguise the data itself. Multiplexing is a technique used to combine multiple signals into one for efficiency in transmission but does not disguise the content of the information. Mixed signal typically pertains to a combination of analog and digital signals within communications, which also doesn't imply disguising the information. Therefore, scrambling stands out as the effective technique specifically aimed at making information unintelligible to unauthorized users
