CSAT Features Encrypted Coding

One company invests in microprinting to encrypt against cloning.

CSAT America (Louisville, CO) has launched encrypted data coding as an anticounterfeiting feature with its printing solutions. The encryption solution is provided as a module in the TASC desktop publishing Windows-based software. CSAT is also featuring microtext printing capability, with its DTS 1200 blister printing machine.

CSAT printing solutions feature encrypted data coding and microtext printing. Up to 20 unique codes can be encrypted in real time.

“Up to 20 unique codes per package can be encrypted in real time, using cryptographic math functions,” says Joseph Buono, sales manager, CSAT America.

The encryption system prevents an end-user from cloning codes for counterfeiting purposes. Variable input data encompass the expiry date, drug identification number, and a secret key code. The data are scrambled, or hashed, to create a new code that appears random to the end-user. The user cannot trace back to the original input values without knowledge of the encryption key.
“CSAT printer software using the secret key generates a unique identity code for the package, which is comparable to a random number,” Buono adds. “The hash function continuously scrambles the data into random patterns. When the end-user scans the Data Matrix code, the output value is the encrypted code [along with] the other variable data.”

CSAT printers use electrophotographic printing in which images are created with a dry toner on a photoconductive drum, then transferred via electrical charge to the substrate. The flash fusing of the dry powder toner avoids downtime required for curing print.

The DTS 1200 prints microtext with character heights of 0.3 mm at 1200 dpi. Printed in the lid stock over each blister cavity, the text remains clearly readable after blister sealing, CSAT says. ■
