Use Case 7


  • It is vital that the database maintain the anonymity of students and, if they so choose, faculty and their institutions.
  • Under no circumstances will identified data be returned in a query.
  • Further, faculty must remove all identifying information in student responses - at this time, the database cannot take responsibility for de-identifying student responses.


  • The database must have a hashing algorithm.

Basic Course of Events

  • Faculty member will upload a spreadsheet with student response data and student identifiers.
  • The faculty member will identify the column with student ids.
  • The student ids will be hashed on upload.
  • Future queries of this data will NOT return the hashed value. Instead, each student will be randomly assigned a number, which will vary on every query.

  • Faculty member will upload student response data.
  • Before final submittal of the data, the faculty member will have to verify (check a box at the end of a statement) that no identifying information about the student will be uploaded.
