RFID医疗试剂防伪管理

状况

Iris Diagnostics(纽约证券交易所Beckman Coulter分部:BEC)是加州一家医疗确诊制作商,该公司期望将一个根据rfid的认证体系集成到其iQ200主动尿液剖析体系中,为了保证只要经过认证的试剂配方薄片,Iris出产的产品与机器一同运用。

该公司决议开发一个认证体系,以避免冒充试剂。假如在虹膜尿液剖析体系中引进假试剂,或许会给该公司带来严峻的安全和财政问题。假如运用假试剂,虹膜确诊学将无法验证尿液剖析测验成果的有效性。这或许对患者构成严峻威胁,由于它或许导致根据过错测验成果的误诊。因而,要求患者再次去医院,从头进行查看。为了避免冒充试剂对公司形成潜在的财政和名誉影响,Iris主动联络JADAK,以确认RFID解决方案。

成果

Iris Diagnostics的iQ200主动尿液剖析体系经过塑料管将测量到的试剂薄片吸入主剖析机。在机器周围的车厢里放着一堆薄板瓶。当一切的薄片都从一个瓶子里抽出来时,技能人员就把它取出来,把管子装进一个新的瓶子里。

该公司期望在运用程序中运用高频RFID标签,由于它期望读取规模很短,以保证只读取离阅览器最近的瓶子上的标签。

Iris与JADAK协作,将Skyetek M2高频RFID读取模块集成到尿液剖析体系中。JADAK还向Iris提出了RFID标签的主张。然后Iris、JADAK和启用rfid标签的供货商以及打印机编码器协作,确认了一种解决方案,该解决方案利用在每瓶薄片上放置启用rfid标签。

打印机编码器运用Skyetek M2阅览器用嵌入式ICODE SLI应答器对标签进行编码。读取器经过ISO 13485认证,应答器契合ISO 15693规范,适用于项目级盯梢和安全运用。

JADAK解决方案完成了一种共同的安全/密钥交流算法,以避免接口的向后工程。该解决方案还答应长途字段晋级加密密钥和算法,以防它们遭到损害。

Skyetek M2问询器读取编码到每个瓶子标签内镶嵌物的数据,在Iris制作工厂打印标签时查看编码到标签上的数字签名。读者能够运用主密钥解锁此签名,运用根据键控散列音讯身份验证代码(HMAC)的加密技能。假如没有看到数字签名,问询器将制止体系将试剂从瓶子中取出,并向机器的技能人员宣布警报,提高了试剂是冒充的或许性。

Iris和JADAK协作为运转在JADAK reader软件上的认证体系编写软件。该体系还运转尿检阅览器和打印机编码器中运用的其他程序,由于它们同享一个加密密钥基础设施。


RFID FOR MEDICAL DEVICES

Iris Diagnostics Uses RFID for Authentication

Situation

Iris Diagnostics (a division of Beckman Coulter, NYSE: BEC), a California manufacturer of medical diagnostic devices, wanted to integrate an RFID-based authentica?tion system into its iQ200 Automated Urinalysis System to ensure that only the certified reagent formula Lamina, which Iris produces, is used with the machine.

The company decided to develop an authentication sys?tem to protect against counterfeit reagents. If a counterfeit reagent were introduced to the Iris urinalysis system, it could raise serious safety and financial concerns for the company. If counterfeit reagents were used, Iris Diagnostics would not be able to verify the validity of the urinalysis test results. This could pose a serious threat to patients, since it could lead to a misdiagno?sis based on faulty test results. Thus requiring patients to revisit hospitals and have tests rerun. To avoid the potential financial and reputational impact of counterfeit reagents to the company, Iris proactively reached out to JADAK to identify a RFID solution.

Results

Iris Diagnostics’ iQ200 Automated Urinalysis System draws a measured amount of the reagent Lamina into the main analysis machine through plastic tubing. A stock of Lamina bottles is held in a carriage next to the machine. When all of the Lamina is drawn out of a bottle, a technician removes it and places the tube in a new bottle.

The company wanted to use high frequency RFID tags for the appli?cation because it wanted a short read range to ensure that only the tag on the bottle closest to the reader was read.

Iris worked with JADAK to integrate the Skyetek M2 high-frequency RFID reader module into the urinalysis system. JADAK also made RFID tag recommendations to Iris. Then Iris, JADAK, and the provid?er of the RFID-enabled labels and printer-encoders collaborated to identify a solution that utilized placement of RFID-enabled labels on each bottle of Lamina.

The printer-encoder used the Skyetek M2 reader to encode labels with embedded ICODE SLI transponders. The reader was ISO 13485 certified, and the transponders were compliant with the ISO 15693 standard and designed for item-level tracking and security applications.

The JADAK solution implemented a unique security/key exchange algorithm to prevent backwards engineering of the interface. The solution also allowed for remote field upgrading of the cryptographic keys and algorithms, in the event they were ever compromised.

The Skyetek M2 interrogator reads the data encoded to the inlay inside each bottle’s label, checking for a digital signature encoded to the label when it was printed at the Iris manufacturing facility. The reader can unlock this signature using a master key, with cryptography based on a keyed hash-message authentication code, or HMAC. If it doesn’t see the digital signature, the interrogator will prohibit the system from drawing the reagent out of the bottle and send an alert to the machine’s technician, raising the possibility that the reagent is counterfeit.

Iris and JADAK partnered to write the software for the authentication system, which runs on JADAK’s reader software. The system also runs the urinalysis reader and others used in the printer-encoders, since they share a cryptographic key infrastructure.
