RFID for anonymous biological samples and pseudonyms

We describe a sample data encryption method and prototype system using RFID (Radio Frequency IDentification) technology for anonymous biological samples and samples with pseudonyms. This method has been developed to improve sample logistics in high-throughput biological laboratories and large-scale biorepositories. An innovative hardware and software concept is presented which allows the (reversible and irreversible) encryption of sensitive sample data without the need of electronic connectivity. The technique allows complete or partial encryption of specific information blocks. This is useful for collaborative sample and data exchange between decentralized laboratories and biorepositories. Further possible uses include system-to-sample authentication or secure data access based on a four-eye principle.
