The use of textronic RFID transponders (RFIDtex tags) offers completely new possibilities in designing household appliances. Their implementations in technologies of washing or ironing textiles are very promising. Specific information on maintaining clothes can be stored in the memory of RFIDtex tags that are permanently bound to the products. This information can be read by washing or ironing devices and then can be used to automatically select the best program or mode of machine operation. Since RFID technology is becoming more and more common, the solution seems simple and ordinary. Nevertheless, there are some barriers that prevent the popularization of such applications. Reliability and efficiency of identification are major concerns, especially near surrounding objects, such as other tags, material composition of textiles, and above all, metal drums of washing machines. The main purpose of the presented work is to propose the communication model in the anti-collision dynamic RFID system, dedicated to use in future intelligent industrial and home washing machines. To develop the elaborated idea, the washing machine demonstrator equipped with read/write RFID devices was designed. Moreover, the RFIDtex transponders according to the authors' conception (restricted under Polish patent, No. PAT.231291) are used in experimental stages. As part of the work, appropriate reading and scanning algorithms were developed to manage multiple data readings from tags inside the drum. Also, measurements were carried out to confirm the identification efficiency in such an Internet of Textile Things (IoTT) system basing on the RFIDtex tags that are placed inside the demonstration washing machine.

“…With offline serialization and online identification, the effect of unknown tags is reduced. In [29], Chen et al presented an efficient and accurate protocol to identify missing tags in high dynamic RFID systems. They combined the reply slot location and reply bits of tags for simultaneous missing tag identification and unknown tag filtering.…”

Retailers grapple with inventory losses primarily due to missing items, prompting the need for efficient missing tag identification methods in large-scale RFID systems. Among them, few works considered the effect of unexpected unknown tags on the missing tag identification process. With the presence of unknown tags, some missing tags may be falsely identified as present. Thus, the system’s reliability is hardly guaranteed. To resolve these challenges, we propose an efficient early-breaking-estimation and tree-splitting-based missing tag identification (ETMTI) protocol for large-scale RFID systems. ETMTI employs innovative early-breaking-estimation and deactivation methods to swiftly handle unknown tags. Subsequently, a tree-splitting-based missing tag identification method is proposed, employing a B-ary splitting tree, to rapidly identify missing tags. Additionally, a bit-tracking response strategy is implemented to reduce processing time. Theoretical analysis is conducted to determine optimal parameters for ETMTI. Simulation results illustrate that our proposed ETMTI protocol significantly outperforms benchmark methods, offering a shorter processing time and a lower false negative rate.

“…The slot index is generated by an irreversible one-way hash function with the input of a tag EPC and a random seed r. If each tag has a distinct hash function, the attackers cannot know the hash function and thus fail to make a perfect counterfeit tag with the same slot index sequence produced by the original one. However, the hash-based scheme assumes the authenticator exactly knowing the hash functions embedded in each individual tag [12], [13], which is very challenging and bring much complexity to the RFID system. A central authentication server is needed for managing the embedded hash functions of each tag, and distribute the hash functions to trust user at needed time.…”

RFID tags are prone to counterfeit attacks in supply chain scenarios. The attacker often uses counterfeit tags to replace stolen tags to avoid being detected by the inventory process.To defend against such attacks, existing hash-based schemes have to know the hash functions embedded in tags, which are usually unavailable in large scale systems. This letter proposes a novel group-based slot constraint (GSC) scheme for lightweight counterfeit tag detection in RFIDenabled supply-chain systems. GSC can be integrated into the identification process by leveraging elaborately designed group hash functions to authenticate tags based on their slot correlation. That is, the tags in the same group can always map to slots with a fixed offset, which offers evidence for identifying counterfeit tags with an abnormal slot index. We also provide a theoretical analysis of the time slots required to achieve the desired accuracy. The simulation results show that GSC provides reliable accuracy without knowing exact hash functions.
