The market change in developed countries around the world towards an older population and the increasing prevalence of chronic disorders result in rising costs in the medical sector [2]. Chronic diseases like COPD, cardiological pathologies or diabetes cause direct costs in addition to a high level of indirect costs [3,4]. A major source of these diseases is the individuals' lifestyle. Low individual physical fitness and a low level of activity paired with mostly unhealthy nutrition are the premiere factors behind life style caused diseases [5]. One strategy to face these challenges could possibly be the reinforcement of primary and secondary prevention and the empowerment of those to take responsibility for their own well-being. By providing mHealth solutions for remote monitoring of health & health and fitness data and integration of social networks for motivation and assistance, this could be achieved by increasing the persons' self-awareness.

This work is part of the Healthy Interoperability research project. Since 2009 a profound knowledge base in the field of telemetry of individual health data has been gained by developing several applications for secure and standardized transport of vital parameters [6]. One major achievement was the implementation of the Continua Health Alliance Design Guidelines [7] which describe a set of internationally established standards and frameworks for mHealth. Since joining the Continua Health Alliance in 2009 the group contributed. WE PUT a pair of store tablets towards the test to locate out which in turn 1 anyone must buy.

The Actual device contains a new seven inch screen, any 1.5 GHz quad-core processoto the progress of this community. The refinements and improvements for chosen standards and frameworks have been observed and implemented.
This paper reports the development of an Hudl Accessories app compliant to the Continua Design addresses and Guidelines the challenges that vendors face during implementation.
2 Methods
Security of usability, interoperability and investments can be ensured using international standards - - for data communication [8]. The Continua Health Alliance uses the ISO/IEEE 11073-20601 standard [9] as the exchange protocol for communicating data in Personal Area Networks (PANs) and Local Area Networks (LANs). This standard defines generic data structures for personal health data, common services available during communication and an optimized transfer syntax and protocol for the exchange of data and control information. Semantic interoperability is gained through the usage of the ISO/IEEE 11073-10101 nomenclature standard and by the introduction of "Device Specializations" defining a set of basic data and capabilities definitions for each device class, e.g. the device class specific standard configuration.

On top of the transport layer, the Accessories for hudl app incorporates an ISO/IEEE 11073 coding engine (X73 Manager depicted in Image 1), which allows encoding/decoding of byte arrays coded compliant to the Medical Device Encoding Rules in order to provide capabilities to exchange communications according to the Optimized Exchange Protocol. You'll acquire some surprisingly accomplished components for the money, nevertheless the Tesco Hudl fails to really wow in nearly any department apart from your The Particular Tesco Hudl is surely an extremely desirable Android tablet in which comes with excellent specs and an incredible 199 price tag. Study our Tesco Hudl ...In this first version, the coding engine supports the standard configurations found in the corresponding ISO/IEEE device specialization documents of the weighting scale, pulse oximeter and blood pressure monitor
The measured values from the individual health devices (measurement parameter, measurement value, physical time and unit stamp as well as information on the PHD itself) are decoded from the received byte streams and mapped to a data structure called HIO DataContainer. By using this generic data container, which was developed for the HIO Software-Framework [10], the app is prepared for further future and expansions functionalities.
Integrating the Healthcare Enterprises (IHE) technical frameworks (TF) [11,12] are referenced by the Continua Health Alliance Design Guidelines for transmitting data further over Wide Area Networks (WANs) as well as to Health Reporting Networks (HRNs) for storage in form of CDA documents. For point-to-point communication between the application hosting device (AHD, e.g. smartphone) and a WAN-Device, the IHE DEC (Device Enterprise Communication) profile defined in the IHE PCD (Patient Care Device) technical framework serves as a basis for the Continua Health Alliance Design Guidelines. Apart from the specification by the DEC-Profile in the IHE PCD technical framework, there are additional restrictions which need to be fulfilled to be Continua compliant.
From the HIO DataContainer the data is passed to the Device Observation Reporter (DOR)-Instance, which includes the HL7 V2.6 processor. The HL7 processor generates appropriate HL7 V2.6 messages according the Continua Health Alliance Design Guidelines, using the information held within the HIO DataContainer. Subsequently the prepared message is transmitted to the WAN-Receiver described by the Continua Health Alliance Design Guidelines.

Further capabilities have been implemented due to the constraints defined by the current version of the Continua Design Guidelines. The Continua Health Alliance demands using a secure connection on the transport layer level, i.e. providing TLS. Therefore, the authentication between the IHE-Actors on a software component level is implemented using certificates and as an appropriate cipher suite TLS_RSA_WITH_AES_128_CBC_SHA is used by the Hudl Accessories app. In order to conform to the Continua Health Alliance Design Guidelines in respect to security requirements for WAN-communication, OASIS SAML (Security Assertion Markup Language) [13] shall be supported for Entity Identity Assertion. Therefore, the IHE ITI Profile XUA (Cross-Enterprise User Assertion) is used as a basis for integrating SAML-Tokens into existing Web service communications, like the PCD-01 Communicate PCD Data transaction (CommunicatePCDData request) used within the DEC-Profile.
There are two options for generating this SAML-Assertion: It can be built within the Accessories for hudl app or requested from an appropriate external Secure Token Service (STS) as specified in WS-Trust [14]. In Java on JSE or J2EE platforms 3rd part libraries are available for either option. As a step to implementation these libraries were therefore evaluated and it was attempted to port them to the Hudl Accessories platform.
The Accessories for hudl app was designed for mobile devices running Hudl Accessories 4. [15] or above as these versions implement the Bluetooth Health Device Profile (HDP). The Galaxy Nexus smartphone, Samsung Electronics Austria GmbH [16], one of the first phones implementing Android 4., was used as a development platform for the Android app. As a development environment Eclipse Indigo version 3.7.2 [17] with the appropriate Android-Plug-in supported by Google was used.

Integration tests were performed with existing professionalindividual wellness devices by single stepping through the data and configuration transmission procedures because they are defined in - Screen Protectors for Hudl - the Continua Design Guidelines PAN and WAN interfaces. The resulting data communications were manually reviewed.
3 Results
The developed Accessories for hudl 4. application was tested and implemented successfully with the blood pressure monitor UA-767PBT-C, A&D Company Ltd. [18], the weighting scale UC-321PBT-C, A&D Company Ltd. [19], and the pulse oximeters PureSAT 9560BT, Nonin Medical Inc.[18].
The SAML libraries could not be ported from JSE/J2EE to the Hudl Accessories platform without modifying the operating system. Therefore a SAML Web service client including appropriate SAML-processing were implemented within the Android app. The SAML-Assertions were claimed from an appropriate Secure Token Service and added into the SOAP-Header of the PCD-01 SOAP request.
