“…The phase information of backscattered RFID signals has been explored in many applications, such as gesture recognition [21], [22], action recognition [23], [24], orientation tracking [25], mechanical features sensing [26], [27], and localization [28]. RF-Rhythm is the first work to extract a tapping rhythm from backscattered RFID signals and is orthogonal to the above work.…”

Passive RFID technology is widely used in user authentication and access control. We propose RF-Rhythm, a secure and usable two-factor RFID authentication system with strong resilience to lost/stolen/cloned RFID cards. In RF-Rhythm, each legitimate user performs a sequence of taps on his/her RFID card according to a self-chosen secret melody. Such rhythmic taps can induce phase changes in the backscattered signals, which the RFID reader can detect to recover the user's tapping rhythm. In addition to verifying the RFID card's identification information as usual, the backend server compares the extracted tapping rhythm with what it acquires in the user enrollment phase. The user passes authentication checks if and only if both verifications succeed. We also propose a novel phase-hopping protocol in which the RFID reader emits Continuous Wave (CW) with random phases for extracting the user's secret tapping rhythm. Our protocol can prevent a capable adversary from extracting and then replaying a legitimate tapping rhythm from sniffed RFID signals. Comprehensive user experiments confirm the high security and usability of RF-Rhythm with false-positive and false-negative rates close to zero.

Localization of Moving Objects Based on RFID Tag Array and Laser Ranging Information

RFID (radio-frequency identification) technology is rapidly emerging for the localization of moving objects and humans. Due to the blockage of radio signals by the human body, the localization accuracy achieved with a single tag is not satisfactory. This paper proposes a method based on an RFID tag array and laser ranging information to address the localization of live moving objects such as humans or animals. We equipped a human with a tag array and calculated the phase-based radial velocity of every tag. The laser information was, first, clustered through the DBSCAN (Density-Based Spatial Clustering of Applications with Noise) algorithm and then laser-based radial velocity was calculated. This velocity was matched with phase-based radial velocity to get best matching clusters. A particle filter was used to localize the moving human by fusing the matching results of both velocities. Experiments were conducted by using a SCITOS G5 service robot. The results verified the feasibility of our approach and proved that our approach significantly increases localization accuracy by up to 25% compared to a single tag approach.

“…Xie et al [11] proposed a RF (Radio Frequency)-glove, which is composed of five tags, to recognize concurrent multiple finger micromovement. Zou et al [12] proposed a device-free gesture recognition system by exploiting phase information of RFID signals and Bu et al [13] turned an ordinary object into a human–machine interface device by attaching a tag array on its surface and tracking its movement by phase variations. In [14], body movement information is collected by the received signal strength (RSS) of RFID tags on different body segments.…”

“…Hsieh et al proposed touch sensor pads, based on RFID through controlling the on and off state of the tag with finger touch [17], and an RFID contact switch through a magnetic connector coupled with the antenna and the chip [18]. Unlike the HMI tag designs in the literature [10,11,12,13,14,15,16], in these two works, the state of the proposed tag can be recognized directly by the code received by the RFID reader, but not by relevant physical information of signals, while no complex data processing is needed. However, their push/press forces were applied on or very close to the chip, which may easily lead to damaging the chip or a fracture/displacement of the bonding and may greatly affect the durability of tags.…”

Radio frequency identification (RFID) has shown its potential in human–machine interaction thanks to its inherent function of identification and relevant physical information of signals, but complex data processing and undesirable input accuracy restrict its application and promotion in practical use. This paper proposes a novel finger-controlled passive RFID tag design for human–machine interaction. The tag antenna is based on a dipole antenna with a separated T-match structure, which is able to adjust the state of the tag by the press of a finger. The state of the proposed tag can be recognized directly by the code received by the RFID reader, and no complex data processing is needed. Since the code is hardly affected by surroundings, the proposed tag is suitable to be used as a wireless switch or control button in multiple scenarios. Moreover, arrays of the proposed tag with rational tag arrangements could contribute to a series of manual control devices, such as a wireless keyboard, a remote controller, and a wireless gamepad, without batteries. A 3 × 4 array of the finger-controlled tag is presented to constitute a simple passive RFID keyboard as an example of the applications of the proposed tag array and it refers to the arrangement of a keypad and can achieve precise, convenient, quick, and practical commands and text input into machines by pressing the tags with fingers. Simulations and measurements of the proposed tag and tag array have been carried out to validate their performances in human–machine interaction.
