It enables telepsychotherapy sessions in which the patient exercises therapy-relevant behaviors in their home environment under the remote supervision of the therapist. Wearable sensor information (electrocardiogram (ECG), movement sensors, and eye tracking) is streamed in real time to the therapist to deliver objective information about specific behavior-triggering situations and the stress level of the patients. We describe the IT infrastructure of the system which uses open standards such as WebRTC and OpenID Connect (OIDC). We also describe the system\u2019s security concept, its container-based deployment, and demonstrate performance analyses. The system is used in the ongoing study SSTeP-KiZ (smart sensor technology in telepsychotherapy for children and adolescents with obsessive-compulsive disorder) and shows sufficient technical performance.<\/jats:p>","DOI":"10.3390\/s22249589","type":"journal-article","created":{"date-parts":[[2022,12,8]],"date-time":"2022-12-08T03:35:53Z","timestamp":1670470553000},"page":"9589","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The SSTeP-KiZ System\u2014Secure Real-Time Communication Based on Open Web Standards for Multimodal Sensor-Assisted Tele-Psychotherapy"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5479-3315","authenticated-orcid":false,"given":"Jonas","family":"Primbs","sequence":"first","affiliation":[{"name":"Department of Computer Science, University of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1537-1336","authenticated-orcid":false,"given":"Winfried","family":"Ilg","sequence":"additional","affiliation":[{"name":"Section for Computational Sensomotorics, Department of Cognitive Neurology, University of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6095-6942","authenticated-orcid":false,"given":"Annika","family":"Thierfelder","sequence":"additional","affiliation":[{"name":"Section for Computational Sensomotorics, Department of Cognitive Neurology, University of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"given":"Bj\u00f6rn","family":"Severitt","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"given":"Carolin Sarah","family":"Hohnecker","sequence":"additional","affiliation":[{"name":"Child and Adolescent Psychiatry, University Medical Center of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"given":"Annika Kristin","family":"Alt","sequence":"additional","affiliation":[{"name":"Child and Adolescent Psychiatry, University Medical Center of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"given":"Anja","family":"Pascher","sequence":"additional","affiliation":[{"name":"Child and Adolescent Psychiatry, University Medical Center of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8484-8639","authenticated-orcid":false,"given":"Ursula","family":"W\u00f6rz","sequence":"additional","affiliation":[{"name":"Business Unit IT, University Medical Center of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6676-1545","authenticated-orcid":false,"given":"Heinrich","family":"Lautenbacher","sequence":"additional","affiliation":[{"name":"Business Unit IT, University Medical Center of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8061-0209","authenticated-orcid":false,"given":"Karsten","family":"Hollmann","sequence":"additional","affiliation":[{"name":"Child and Adolescent Psychiatry, University Medical Center of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5019-8073","authenticated-orcid":false,"given":"Gottfried Maria","family":"Barth","sequence":"additional","affiliation":[{"name":"Child and Adolescent Psychiatry, University Medical Center of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"given":"Tobias","family":"Renner","sequence":"additional","affiliation":[{"name":"Child and Adolescent Psychiatry, University Medical Center of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3216-1015","authenticated-orcid":false,"given":"Michael","family":"Menth","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of T\u00fcbingen, 72076 T\u00fcbingen, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"167","DOI":"10.1037\/cps0000056","article-title":"The efficacy of synchronous teletherapy versus in-person therapy: A meta-analysis of randomized clinical trials","volume":"29","author":"Lin","year":"2022","journal-title":"Clin.
