Which of the following technologies allows for secure sharing of information?

Homomorphic encryption is a powerful technology that enables computations to be performed on encrypted data without needing to decrypt it first. This means that sensitive information can be processed securely in its encrypted form, allowing for secure sharing of data among different parties without exposing the raw data itself.

The ability to perform operations on encrypted data allows organizations to leverage third-party services or cloud computing without compromising data privacy. For example, a company could outsource data analysis to a cloud service and still maintain confidentiality since the data remains encrypted throughout the process. This makes homomorphic encryption particularly valuable in scenarios where privacy and data security are critical, such as in healthcare, finance, and other regulated industries.

In contrast, other technologies mentioned have different purposes. Data masking is typically used to obfuscate specific data elements while preserving the overall structure, useful in environments like testing or development but not enabling operations on the data itself. Tokenization replaces sensitive data with unique identifiers (tokens) but usually requires a mapping to retrieve the original data, limiting its use for sharing in a secure way. Basic encryption secures data by making it unreadable without decryption keys, but it doesn’t support operations on the data without prior decryption, unlike homomorphic encryption. Thus, homomorphic encryption is the most
