A non-transitory machine-readable storage medium comprising instructions, which when implemented by one or more machines, cause the one or more machines to perform operations comprising:
- obtaining, via one or more graphical user interface, a plurality of electronic data submissions, each electronic data submission having user identification information and a corresponding confidential data value;
- storing each of the electronic data submissions in a row of a submission table by encrypting the user identification information using a first cryptographic key and storing the encrypted user identification information in a first column of the submission table, and encrypting the confidential data value using a second cryptographic key different than the first cryptographic key and storing the encrypted confidential data value in a second column of the submission table, thereby deidentifying the confidential data values;
- obtaining, for a first organization, information about transitions made by employees of the first organization to another organization or from another organization to the first organization;
- calculating, for a particular organization of a plurality of organizations other than the first organization, a total number of transitions between the particular organization and the first organization;
- for a combination of the first organization and the particular organization in the plurality of organizations other than the first organization, calculating a peer score based on the total number of transitions between the particular organization and the first organization;
- identifying the particular organization as part of a peer organization group with the first organization based on the calculated peer scores;
- obtaining a deidentified set of confidential data values for the first organization using the submission table;
- determining that the deidentified set of confidential data values for the first organization contains fewer values than a predetermined threshold for providing a statistical insight;
- in response to the determining, inferring one or more confidential data values for the first organization using one or more confidential data values for one or more organizations, other than the first organization, in the peer organization group;
- calculating a statistical insight based on the inferred one or more confidential data values;
- and
- causing display of the statistical insight in a graphical user interface rendered on a display.
