}As indicated above, the blood test result actually contains several sensitive information on the patient, such as the blood type, DNA information, home address, and contact information.
However, Namaste Tech only wants to know if the user has no history of Amphetamine and Cocaine use. Sending the entire blood test to Namaste Tech is not only unnecessary but also reveals sensitive information about the user, which over time can leak out of Namaste Tech’s database, thus compromising the privacy of the user.
