SOLVED. Adult Science Fiction about decoding a message to save the world? [s]

[Tautvydas]

Plot: it’s a science fiction book. Possibly about a secret project. A scientist dies and wispers a message which then is used to decode some kind of a code to maybe save the world. I think the scientist that dies has a japanese name or sirname. The project might be about a super computer that is sabotaged.

How long did you read it? A range of years is fine

[Tautvydas]

Read it around 15 years ago, but i don’t think it was a new book at that time.

It sounds very much like Digital Fortress by Dan Brown.
