Diamond-based tradeable instrument security system
View Patent ↗A tradeable commodity or instrument, a trading system for a plurality of such commodities, a method of trading using such a system and security systems related thereto. The tradeable instrument comprises a secure container constituted by a transparent cover ( 12 ), a stone holder pad ( 14 ), a set of diamonds ( 15 ), a diamond or stone holder ( 16 ), a data card ( 18 ), a bottom cover ( 20 ) and a tamper evident band ( 22 ) interconnected into a secure, tamper-evident envelope. The data card ( 18 ) incorporates physical and digital security features. In addition, at least one externally readable programmable logic device is incorporated in the tradeable instrument card. The tamper evident band ( 22 ) is shrunk onto the tradeable instrument card and includes physical security features in the form of holographic foils incorporated in the band.
1. A tradeable instrument comprising:
a secure tamper evident envelope within which a plurality of relatively similar, individually non-uniform, non-standard valuable items are securely contained,
wherein the plurality of relatively similar, individually non-uniform, non-standard valuable items are each selected based on their declared value according to a declared valuation method, and are included in the secure tamper evident envelope such that the sum of the declared values of the plurality of relatively similar, individually non-uniform, non-standard valuable items within the secure tamper evident envelope is substantially equal to a declared value of the tradeable instrument and the sum of the declared values of substantially similar valuable items contained in one or more similar, like valued tradeable instruments;
the secure tamper evident envelope comprises a first externally readable digital data store that comprises first data stored therein, the first data comprising physical attribute data specifying unique physical attributes of each of the plurality of individually non-uniform, non-standard valuable items contained within the envelope;
the secure tamper evident envelope is in the form of a container comprising two halves that are secured together at a joint there between, so as to envelop the plurality of relatively similar, individually non-uniform, non-standard valuable items; and
the tradeable instrument further comprises a tamper evident band secured over the joint, the tamper evident band comprising a second digital data store.
2. The tradeable instrument of claim 1 , wherein the second digital data store comprises second data stored therein, the second data comprising certificate data and physical attribute data of each of the plurality of relatively similar, individually non-uniform, non-standard valuable items.
3. The tradeable instrument of claim 2 , wherein the second data comprises encrypted data, the encrypted data comprising said certificate data and physical attribute data.
4. The tradeable instrument of claim 1 , in which the plurality of relatively similar, individually non-uniform, non-standard valuable items are low mass, high value items which are securely disposed within the container.
5. The tradeable instrument of claim 1 , wherein the plurality of relatively similar, individually non-uniform, non-standard valuable items are diamonds.
6. The tradeable instrument of claim 5 , wherein the physical attribute data of said first data specifies physical attributes of said diamonds.
7. The tradeable instrument of claim 3 , wherein:
the plurality of relatively similar, individually non-uniform, non-standard valuable items are diamonds; and
the physical attribute data in said first data and said second data specifies physical attributes of said diamonds.
8. The tradeable instrument of claim 1 , wherein said first digital data store is selected from a programmable logic device, a magnetic strip, and a bar code.
9. The tradeable instrument of claim 8 , wherein said first digital data store is a programmable logic device, the programmable logic device selected from the group consisting of an externally readable transponder microchip and a radio frequency identification (RFID) tag.
10. The tradeable instrument of claim 8 , wherein:
said tamper evident band is a shrink fit band that is disposed around a periphery of the container; and
said second digital data store comprises second data stored therein, the second data comprising encrypted data, the encrypted data including physical attribute data of each of the plurality of each of the plurality of relatively similar, individually non-uniform, non-standard valuable items.
