Abstract
An inexpensive encryption device, system and method includes coded alphanumeric characters preprinted according to different key codes or mail-out forms that can be manipulated by a prospective user to yield encrypted data that can be returned over unsecure transmission channels for secure decryption by the operator of a computer-secured operating system.
Claims15
A data encryptor apparatus comprising:
- a first array of alphanumeric characters disposed on a carrier;
- a selectively-removable coating disposed to cover over and obscure the first array of alphanumeric characters on said carrier;
- a second array of alphanumeric characters that are disposed on said coating for selective removal by scratching away said coating and that are in character-by-character fixed spatial relationship to the characters in the first array beneath said coating, which characters in the first array are arranged to be exposed in response to selective removal of regions of the coating associated with spatially corresponding characters of the second array;
- and,
- a key code means disposed on the carrier for identifying the relationship between said alphanumeric characters in said first and second alphanumeric arrays.

A method for producing a data encryptor device comprising the steps of:
- forming a plural number of random arrays of data characters with an identifying keycode associated with each array;
- storing the plural number of arrays and associated keycodes;
- accessing selected sets of arrays and associated keycodes to form an encryptor set of arrays with associated keycodes;
- printing the encryptor set of arrays with associated keycodes on a substrate;
- obscuring the encryptor set of arrays with a coating which is selectively removable by scratching away said coating for exposing the same on the substrate;
- and
- printing alphanumeric characters on the coating in fixed spatial registration with the data characters to provide a data encryptor that translates selected alphanumeric characters to the spatially-corresponding data characters in response to selective removal thereof by scratching off said coating from the regions of the coating at locations thereon at which said selected alphanumeric characters are printed.

A data encyptor apparatus comprising:
- a plurality of segregated first arrays of alphanumeric characters disposed on a carrier;
- a selectively-removable coating disposed to cover over and obscure the plurality of first arrays of alphanumeric characters on said carrier;
- a plurality of segregated second arrays of alphanumeric characters disposed on said coating for selective removal by scratching away said coating;
- each second array being in character-by-character fixed spatial relationship to the characters in the corresponding first array beneath said coating, which characters in each of said first arrays are arranged to be exposed in response to selective removal by scratching away of regions of the coating associated with spatially corresponding characters in each of said second arrays;
- each of the plural number of the segregated first and second arrays of characters corresponding to one character-place of a multi-character data word;
- and,
- key code means disposed on the carrier for identifying the relationship between said alphanumeric characters in each of said first and second arrays of alphanumeric characters.

A data encryptor apparatus comprising:
- a first array of alphanumeric characters disposed on a carrier;
- a selectively-removable coating disposed to cover over and obscure the first array of alphanumeric characters on said carrier;
- a second array of alphanumeric characters adjacent to said first array of alphanumeric characters, said alphanumeric characters in said second array being in character-by-character fixed spatial relationship to the characters in the first array beneath said coating, which characters in the first array are arranged to be exposed in response to selective removal of regions of the coating associated with spatially corresponding characters of the second array;
- and,
- a key code means disposed on the carrier for identifying the relationship between said alphanumeric characters in said first and second alphanumeric arrays.

A data encyptor apparatus comprising:
- a plurality of segregated first arrays of alphanumeric characters disposed on a carrier;
- a selectively-removable coating disposed to cover over and obscure the plurality of first arrays of alphanumeric characters on said carrier;
- a plurality of segregated second arrays of alphanumeric characters, each of said second arrays of alphanumeric characters being disposed adjacent to one of said plurality first arrays of alphanumeric characters, each of said second arrays of alphanumeric characters in said second array being in character-by-character fixed spatial relationship to the characters in the corresponding first array beneath said coating, which characters in each of said first arrays are arranged to be exposed in response to selective removal by scratching away of regions of the coating associated with spatially corresponding characters in each of said second arrays;
- each of the plural number of the segregated first and second arrays of characters corresponds to one character-place of a multi-character data word;
- and,
- a plurality of key code means disposed on the carrier for identifying the relationship between said alphanumeric characters in each of said first and second arrays of alphanumeric characters.

- and
- printing alphanumeric characters adjacent to the alphanumeric characters obscured by the coating in fixed spatial registration with the obscured alphanumeric characters to provide a data encryptor that translates selected alphanumeric characters to the spatially-corresponding data characters in response to selective removal thereof by scratching off said coating from the regions of the coating at locations adjacent to the location where said selected alphanumeric characters are printed.
