Which of the following is a major concern regarding the management of personal information by third parties?

The major concern regarding the management of personal information by third parties is a lack of transparency. When individuals share their personal information with external entities, they often lose visibility into how that information will be used, stored, and protected. This lack of transparency can lead to significant risks, as consumers may not be fully informed about the potential for misuse of their data, such as identity theft or unauthorized selling of their personal information to other companies.

Transparency is crucial for building trust between consumers and third-party organizations. Without clear communication about data handling practices and privacy policies, consumers cannot make informed decisions about whether to share their information. This concern is exacerbated by incidents of data breaches where personal information can be exposed, further highlighting the importance of transparency in personal data management.

While increased costs for consumers, better data sharing capabilities, and improved customer service are relevant to discussions about third-party data management, they do not capture the overarching concern of trust and safety that arises from a lack of transparency.
