Legal requirements related to data security typically involve laws that protect people’s right to privacy as well as establishing standards for handling protected health information (PHI). These regulations vary from country to country but generally require organizations to take appropriate measures in order secure patient records – such as limiting access only those who need it and using firewalls or encryption technology when transmitting files across networks. Client confidentiality requires that practitioners do not divulge any PHI to anyone without their consent unless they deem it necessary for the person’s care. In order to ensure success, all these principles need to be considered when creating and maintaining an effective data management system. This will protect patient rights while providing quality care.
