Digital signature technologies allow today to draw up digital writing as do- cument, or proof, on the same basis than paper. Unlike comon lines on “digital trust”, a document’s digital authenticity does not guarantee neither the content truthfulness, nor a blackout of risks if this document is considered : digital trust is not a replacement of human and social trust by technology.
What is in stake in a document is trust towards people or institutions (that once approved it or are witnesses about it). While dealing with these issues, paper laboratory notebooks are emblematic because of their structure and their rules. Digital laboratory notebooks processing allows to challenge their properties with their purpose. After analyzing the notebook’s probation nature, through case law, an interactive display of crytographic signatures will be offered (more spe- cifically trusted timestamping). This contribution falls within the context of the human computer interaction enforcing security. Then, an instrumented docu- ment process is designed to enable the constitution of solid evidences, without hampering the creators’s or innovators’s activity. A beam of miscellaneous tes- ting sessions is deployed to ponder the software, its design, and subsequently all the materialized assumptions and use.
