Abstract
A device for storing a serial string of confidential numbers or letters in public view without compromising the confidentiality or identity of the numbers or letters, yet enabling a person having knowledge of those numbers to recognize and recall their identity. The device comprises a carrier surface and a matrix of contiguous graphic boxes positioned on the carrier surface and having empty spaces for insertion of numerals or letters therein. Each box has alignment with other boxes along at least two diagonals within the matrix. The confidential string of letters or numbers are inserted within empty boxes along one or more diagonals with in the matrix, with the remaining boxes being filled in with random numbers and letters to disguise the identity and location of the confidential sequence.
