An I-Key (Integrity Key or Instance Key) is a unique alphanumeric or numeric string generated for every significant operation in the ASC timetable workflow — for example, when creating a new lecture session, updating a room assignment, or finalizing a weekly schedule. Unlike a simple auto-increment ID, an I-Key is often designed to be unpredictable, time-dependent, and cryptographically resistant to tampering.

A typical ASC I-Key generator might use the following logic:

  • Algorithm:
    I-Key = hash( timestamp || user_id || resource_type || random_nonce )
    where hash could be a truncated SHA-256 or a simpler custom function to produce a 12–16 character string.

  • Output:
    A string like 3F8A2D1C9E4B that is virtually impossible to guess sequentially.

    • For ASC’s batch timetable generation (e.g., creating 200 lecture slots at once), the generator may embed a hybrid approach:

    This ensures that even if two different administrators generate timetables for the same rooms and times, the I-Keys will differ, preventing cross-contamination when merging schedules.
