Masking data within JSON-type documents

1. A method comprising using at least one hardware processor for: receiving input from a user with respect to masking of a data element in one or more documents of a java script object notation (JSON) type, said one or more documents each comprise a hierarchy of at least two levels identified by name-value pairs, wherein the input comprises:

(i) an identifier of the data element, and (ii) one or more constraints for masking the data element based on the hierarchy of the one or more documents of the JSON-type, said one or more constraints define the masking with respect to a level of the at least two levels: and generating a masking rule for the one or more documents of the JSON-type based on the input, wherein the masking role is generated automatically upon completion of the masking rule being defined by the input; wherein the generating of the masking rule comprises generating a script; and the enforcing of the masking rule on the document comprises executing the script on the document.

2. The method of claim 1 , wherein said at least one hardware processor is further used for enforcing the masking rule on a document of the one or more documents of the JSON-type.

3. The method of claim 2 , wherein the enforcing of the masking rule on the document is performed online.

4. The method of claim 3 , wherein the enforcing of the masking rule comprises:

listening to traffic in a network,

identifying the document as it passes through the network, and

enforcing the masking rule on the object.

5. The method of claim 2 , wherein the enforcing of the masking rule on the document is performed offline.

6. The method of claim 1 , wherein the generating of the masking rule comprises generating a script.

7. The method of claim 6 , wherein the language of the script is JavaScript.

8. The method of claim 6 , wherein the language of the script is extended with one or more additional functions.

9. The method of claim 1 , wherein the receiving of the input from the user comprises providing the user with a form to be filled out and wherein the input is received by the form.

10. The method of claim 1 , wherein the receiving of the input from the user comprises providing the user with a display of a document of the one or more documents of the JSON-type and wherein the input is received by a selection made by the user on the display.

11. The method of claim 1 , wherein the one or more documents are selected from the group consisting of: NoSQL queries responses, messages and files.

12. The method of claim 1 , wherein the JSON-type of the one or more documents is selected from the group consisting of: JSON documents and binary JSON (BSON) documents.

13. A method comprising using at least one hardware processor for: receiving a masking rule of a data element in one or more documents of a JSQN-type, said one or more documents each comprise a hierarchy of at least two levels identified by name-value pairs, wherein the masking rule is based on the hierarchy of the one or more documents of the JSON-type, wherein the masking rule is defined according to one or more constraints with respect to a level of the at least two levels; and enforcing the masking rule on a document of the one or more documents of the JSON-type; wherein the enforcing of the masking rule comprises, listening to traffic in a network; identifying the document as it passes through the network; and enforcing the masking rule on the document.

14. The method of claim 13 , wherein the enforcing of the masking rule on the document is performed online.

15. The method of claim 13 , wherein the enforcing of the masking rule on the document is performed offline.

16. A computer program product comprising a non-transitory computer-readable storage medium having program code embodied therewith, the program code executable by at least one hardware processor to: receive input from a user with respect to masking of a data element in one or more documents of a java script object notation (JSON) type, said one or more documents each comprise a hierarchy of at least two levels identified by name-value pairs, wherein the input comprises:

(i) an identifier of the data element, and (ii) one or more constraints for masking the data element based on the hierarchy of the one or more documents of the JSON-type, said one or more constraints defines the masking with respect to a level of the at least two levels; and generate a masking rule for the one or more documents of the JSON-type based on the input, wherein the masking rule is generated automatically upon completion of the masking rule being defined by the input; wherein the generating of the masking rule comprises generating a script; and the enforcing of the masking rule on the document comprises executing the script on the document.

17. The computer program product of claim 16 , wherein said program code is further executable by the at least one hardware processor to enforce the masking rule on a document of the one or more documents of the JSON-type.

18. The computer program product of claim 16 , wherein the generating of the masking rule comprises generating a script.
