Card Data Storm

Card Data Storm is a tool for anyone working with sensitive financial information. For business owners, the app can come in handy to check whether employees illegally store card information on the local drives. The app can also come in handy for personal use, especially if you want to ensure no credit or debit data is saved on your disk.

The idea behind the tool is to perform a deep scan of the hard disk and retrieve every accessible file on the system that is known to contain sensitive data. More precisely, the application thoroughly verifies Excel spreadsheets, word documents, ZIP archives as well as PDF and JPEG files, thanks to its optical character recognition technology. On a side note, the developer plans to add all Microsoft Office document types in the future releases.

Following the scan, the application is designed to check any line of potential card numbers and compare them against a luhn algorithm also known as mod 10 or modulus 10. The luhn algorithm is a complex pattern match used world wide that includes a list of known payment card issuer identification numbers. It goes without saying that the algorithm is constantly reviewed and updated as to reflect the new identification numbers released.

It is worth mentioning that the application supports the common card issuers used across the globe, including, but not limited to Master Card, Visa, Maestro, American Express, Diners Club, RuPay, UATP, Verve, Dankort, Troy, JCB, China Union Pay or LankaPay. In case you cannot find your specific card issuer right away, you should check the Settings.

Considering the nature of the data the application is working with, security cannot be stressed enough. Consequently, the reports provided by Card Data Storm are encrypted and, since the app does not have Internet access capabilities, the data cannot be transferred off the device.
