- Eckoh has been granted a US patent for the transaction security method and system that underpins its CallGuard product.

Eckoh already holds an existing UK patent for its CallGuard On-Site solution which prevents sensitive customer cardholder data from reaching call recordings and contact centre agents by using a DTMF (Dual Tone Multi-Frequency) masking method.

The US patent will enable Eckoh to protect its intellectual property in North America where currently all of its installed US client base use this technology.

Over the next three years the CallGuard On-Site product is expected to continue to account for a significant proportion of sales.
