Privacy of Data

Q1) Identify the main data security aspects in the below categories :)

a-   Need to protect confidentiality of data.

The following are examples of practices that may be implemented to increase the level of confidentiality:

1-     Use study codes on data documents (e.g., completed questionnaire) instead of recording identifying information and keep a separate document that links the study code to subjects’ identifying information locked in a separate location and restrict access to this document (e.g., only allowing primary investigators access);

2-   Encrypt identifiable data;

3-   Remove face sheets containing identifiers (e.g., names and addresses) from survey instruments containing data after receiving from study participants;

4-  Properly dispose, destroy, or delete study data / documents;

5-   Limit access to identifiable information;

6-   Securely store data documents within locked locations; and/or

7-    Assign security codes to computerized records.

b-   Shop security.

In cryptography, encryption is the process of encoding messages or information in such a way that only authorized parties can read it.[1] Encryption doesn't prevent hacking but it reduces the likelihood that the hacker will be able to read the data that is encrypted.[2]:374 In an encryption scheme, the message or information, referred to as plaintext, is encrypted using an encryption algorithm, turning it into an unreadable ciphertext.[2] This is usually done with the use of an encryption key, which specifies how the message is to be encoded. Any adversary that can see the cipher text should not be able to determine anything about the original message. An authorized party, however, is able to decode the cipher text using a decryption algorithm, that usually requires a secret decryption key, that adversaries do not have access to. For technical reasons, an encryption scheme usually needs a key-generation algorithm to randomly produce keys.

c-   Online banking.

1-     Keep your passwords, Personal Identification Number (PIN) and card numbers confidential.
