What is Encryption?

Encryption is the process of making information unreadable to unauthorized viewers. We can encrypt all kinds of content. For example, we can encrypt messages, files, folders, entire devices, and much more.

Why is Encryption Important?

There are regulations governing the handling of protected information and significant penalties for non-compliance. Encryption helps guarantee the safety of a patient’s information and provides a safe harbor for the institution from having to notify patients, the media and the government in the event a breach or other loss of protected health information occurs.

What Information Needs to be Encrypted?

All Protected Health Information must be encrypted. PHI is information related to the provision of past or present healthcare to patients and can include patient name, date of birth, date of service, MRN, invoice number, social security number, address, email address, facial photos or other identifying photos.

What Devices or Platforms Need to be Encrypted?
  • Portable devices – such as flash drives and smart phones.
  • E-mail attachments that contain PHI and go outside the secure Washington University/BJC Healthcare.
  • Laptops
  • Desktops – if protected health information is stored on the hard drive.
