What is Encryption?
• Encryption is a security process that scrambles
information. It changes information from a readable
form into something that can not be read unless you
have the key.
This: Encryption changes data into an unreadable format
Becomes something like this:
Rmvtu[yopm dhqht3w 3qtq isem ze mrxephlebl oermzq
…so ONLY the person with the decryption key or
password can read the information
Encryption vs. Passwords
• Having a password does not necessarily mean
something is encrypted.
– Passwords by themselves do not scramble the information.
• If something is only “password protected,” it is not
enough protection - someone could bypass the
password and read the information.
Password Protected
Why is Encryption Important?
• Laptops and USB devices can be
easily lost or stolen
• Statistics show that as many as one
in ten laptops will be stolen or lost
from an organization over the
lifetime of each computer
Encryption protects confidential information and helps
keep it private!
Why is Encryption Important? (Cont’d)
• HIPAA – Health Insurance
Portability and
Accountability Act to ensure
confidentiality of patient
health information
• Regulatory efforts impose
stiffer fees and fines in the
event that a breach occurs
and steps are not taken to
appropriately protect
sensitive data
• Breach Notification Laws require notification if
information was not
Encryption technologies can assist with ensuring the confidentiality of patient
health information and also serve as a strong measure of protection against
today’s commonly anticipated threats, such as unauthorized access,
modification, and disclosure.
• April, 2014 - OCR levies $2 million in HIPAA
fines for stolen laptops:
– $1,725,220 against Concentra Health Services for
an unencrypted laptop that had been stolen from
one of Concentra Health Services facilities.
– $250,000 against QCA Health Plan, Inc. of
Arkansas after an unencrypted laptop containing
personal health information for 148 people was
stolen from an employee's car.
What to Encrypt?
High Risk Confidential
A person’s name or other
identifier, in conjunction with:
• Personally-identifiable Medical
• Dates (birth date, admission date,
discharge date, etc.)
• Social Security number
• Driver’s license
• State ID or Passport number
• Biometric information
• Medical Record # (MRN)
• Health Insurance #
Other Confidential
• Human Subjects information
• HR Records
• Credit Card Information
• Whatever you
considers confidential

Security – “Isn’t this just an I.T. Problem?”
Good Security Standards follow the “90 / 10” Rule:
10% of security safeguards are technical
90% of security safeguards rely on the computer user
(“YOU”) to adhere to good computing practices
The lock on the door is the 10%. You remembering to
lock, check to see if it is closed, ensuring others do not
prop the door open, keeping control of keys is the 90%.
