Biometric identification services have been applied to almost all aspects of life. However, how to securely and efficiently identify an individual in a huge biometric dataset is still very challenging. For one thing, biometric data is very sensitive and should be kept secure during the process of biometric identification. On the other hand, searching a biometric template in a large dataset can be very time-consuming, especially when some privacy-preserving measures are adopted. To address this problem, we propose an efficient and privacy-preserving biometric identification scheme based on the FITing-tree, iDistance, and a symmetric homomorphic encryption (SHE) scheme with two cloud servers. With our proposed scheme, the privacy of the user’s identification request and service provider’s dataset is guaranteed, while the computational costs of the cloud servers in searching the biometric dataset can be kept at an acceptable level. Detailed security analysis shows that the privacy of both the biometric dataset and biometric identification request is well protected during the identification service. In addition, we implement our proposed scheme and compare it to a previously reported M-Tree based privacy-preserving identification scheme in terms of computational and communication costs. Experimental results demonstrate that our proposed scheme is indeed efficient in terms of computational and communication costs while identifying a biometric template in a large dataset.

Abstract Speech-language pathologists, working in a multicultural, community-based environment for young children with special needs in Vancouver, Canada, collected information on 84 clients using AAC from a chart review. The speech-language pathologists collected additional usage information and attended a group interview to discuss barriers and facilitators of AAC. Thirty-one percent of the children were using AAC. Children aged between 16 and 72 months typically relied on multiple modes of communication, including sign, communication boards and binders, and low- and high-tech communication devices. All of the children used at least one type of unaided mode. Fifty-five percent used pictures or communication boards/displays, and 29% used technology with speech output. Similarities in usage of AAC were noted in home and child-care settings with increased use of unaided in homes and a slightly increased use of aided communication in child care settings. Speech-language pathologists reported that the time needed for AAC intervention as well as limited funding for high-tech devices continue to be major barriers. Additional research is needed to describe current AAC practices with young children particularly from minority linguistic and cultural backgrounds. Stakeholder input is needed to explore perceptions of children's usage of AAC in daily life with familiar and unfamiliar communication partners.

Innovations in technology have resulted in increased use of tablets, mobile devices, and applications as augmentative and alternative communication (AAC) systems for children with complex communication needs (CCN). Although research has been conducted on the specific characteristics of AAC technologies, many interfaces remain replications of prior communication devices with little consideration of the features of newer platforms. A greater concern is that these interfaces may not be based on empirical evidence or derived from key developmental language theories. As such, these interfaces may place additional demands on children with CCN instead of supporting their development of language content, form, and use. The purpose of this paper is to discuss potential interface supports for AAC systems that capitalize on current technologies and draw upon key tenets of developmental theory.

The purpose of this mixed methods study was to determine the barriers that special educator teachers encounter when using iPads within the Life Skills classroom. The research investigates the experiences, frustrations, and barriers through educators’ perceptions of iPad implementation. The influence of these issues suggests why iPad usage is not a device that special education classrooms are using in a widespread daily manner. Exploration of iPads as an educational tool and as a communication device is also discussed, along with considerations of other communications systems such as Picture Exchange Communication Systems and Alternative and Augmented Communication Devices is considered. Recommendations for further possible research are also discussed.
