SentryCard: A Hygienic Biometric Identification Solution

SentryCard Protects Against Data Breaches, Phishing Attacks, and COVID-19

How SentryCard Helps

SentryCard brings together the most cutting-edge biometric identification and cryptographic technology to achieve the following goals:

More Secure Identification and Authorization

Sentry Enterprises built the SentryCard system as a joint project that would provide organizations with absolute identification confidence. Whether team members are accessing enterprise systems onsite or remotely, organizations can trust that SentryCard’s biometric authentication of team members offers proof-positive ID verification at every log-in — based on biometric information that’s impossible to forge.

Biometric Identification Without the Disadvantages

Until SentryCard, enterprises that used biometric access control faced two pressing disadvantages related to (1) biometric data risks and (2) COVID-19 related challenges. For many organizations, these disadvantages were significant enough that it prevented them from using biometric identification as a viable access control solution.

Overcoming Biometric Data Risks

Most biometric identification systems need to save the ultra-sensitive biometric signature information of team members within their data systems. Any breach that exposes this information represents extreme risks and liabilities — both to team members whose biometric data gets exposed and to the organizations that could have their internal systems exposed to hackers as a result.

  • Decentralized: All biometric data is enrolled, stored, and matched entirely within the SentryCard itself. It never touches an external system.
  • Unique: Every SentryCard has its own unique and inaccessible encryption key that protects all biometric data found within the card.
  • Non-transferable: Only one person can use a SentryCard ever. As a single-use solution, once enrolling a team member’s biometric data into the card, no one else can use the card again.
  • Controlled: After issuing a SentryCard, the team member that holds the card has total control over his or her biometric data that is safely stored in the credential.
  • Irretrievable: Biometric data enrollment into the SentryCard is a one-way action. After enrollment, the data cannot be retrieved or changed. Once set, the credential is only capable of providing an affirmative or negative authentication output.

Hygienic Biometric Identification During COVID-19 Related Challenges

The COVID-19 pandemic has made it dangerous — from a hygienic standpoint — to use shared touchpads, which are common in most biometric identification solutions. Also, the need for masks during the pandemic has reduced the effectiveness of many facial identification systems.

  • A unique card that does not require employees to touch shared surfaces: Each SentryCard holder uses the physical SentryCard to verify his or her biometric ID information. This eliminates the need for multiple employees to touch any shared surfaces and reduces the risks of virus transmission.
  • A device that does not rely on facial identification: The SentryCard uses biometric data from a fingerprint scanner found on the card itself. It does not rely on a video camera that might not be able to accurately identify someone wearing a mask.
