OLARTE LOPEZ, Nancy Esperanza  e  RUBIANO FONSECA, Astrid. Biological signals storage system, with remote access and security parameters. Tecnura [online]. 2013, vol.17, n.37, pp.74-83. ISSN 0123-921X.

Abstract This paper shows the design and implementation of a storage system with security parameters intended for biological signals. The system deals with two important aspects. On the one hand, signal processing; on the other hand, software application developments that support telemedicine platforms. The rationale behind the implementation of such systems is the current situations in hospital environments, where there is the need to transmit these signals remotely with the best possible quality so as to provide an effective specialist diagnosis in the shortest time possible. First, within this methodology, ECG conditioning signal was proposed; then, temperature signal processing was also proposed. Additionally, the project considers respiration waveforms, and blood pressure signals are also processed. Different calculations were proposed for signal processing in order to implement circuits with discrete and surface electronic components. The implemented software was created using the Java platform, including security authentication parameters based on specific knowledge (username, password and a secret question answer). This allowed subsequent visualization of several ECG and temperature signals associated with patients. The information captured is centrally stored and managed at the Military University Telemedicine Research Group - TIGUM server - where the whole project was developed. Additionally, the final prototype allows including more protocols, communication technologies for data transmission and reception, as well as security parameters for future implementation.
