Name one common method of ensuring data security for registries.

Implementing encryption protocols is a widely recognized method of ensuring data security for registries. Encryption transforms data into a secure format that can only be read or processed by individuals who have the proper decryption keys. This process protects sensitive information from unauthorized access, ensuring that even if data is intercepted, it remains unintelligible to malicious actors.

By securing data both at rest and in transit through encryption, registries can effectively safeguard personal and confidential information, thus maintaining trust and compliance with various data protection regulations. This practice is integral to maintaining the integrity and confidentiality of the data managed by registries.

The other options do not uphold data security. Open access policies can expose sensitive data to unregulated access, compromising security. Accepting all data submissions without verification increases the risk of fraud and errors, threatening both the integrity and security of the data. Relying solely on paper records lacks the security protocols that digital storage can provide and is also less efficient in terms of data management and retrieval.
