Ethical concerns surrounding data collection practices include issues of privacy, consent, and potential misuse of information. Organizations often collect vast amounts of personal data, raising questions about how this data is stored, used, and shared. There are concerns about lack of transparency, where individuals might not be fully informed about what data is collected or how it will be used. Additionally, data breaches can lead to identity theft and unauthorized access to sensitive information, prompting calls for stricter regulations and ethical standards in data handling.
