The data I have given above together with my own experience as an editor lead me to think that the integrity of current scientific publishing is currently low. There is much room for improvement. We can imagine ways in which computers and electronic publishing might make things worse. It may be easier to copy and fabricate data, to alter the data of others, to manipulate images, or to disguise attempts at fabrication after they are suspected. The sad truth is that if a researcher wants to deceive editors and readers then he or she can do so without much difficulty.
Science operates on trust.
Peer review does not protect against fraud. No system could eradicate fraud within science. Nevertheless, I can see many ways in which electronic publishing could increase the integrity of the scientific record. Scientific papers could be published together with the full raw data plus the software used to analyse the data. Much fuller methods can be published than is usually possible in paper journals.
