**2.5 Declaration of interest**

It was assumed that the book chapter would be written by the Co-Authors as a fully volunteer E-service work (though the notion: work for the Society, used in Poland, performed under control of computer and computer application leading designers), would be much more adequate here, and there will be no conflict of interests nor debts for outsourcing work.

In particular, no Co-Authors may have any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest could include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. The Co-Authors will not have any interests in a summary declaration of interest statement in the manuscript file. The following has been stated: 'Declarations of interest: none'. This summary statement will be ultimately published if the E-service book chapter is accepted for printing.

Human and animal rights): the project will be performed in accordance with The Code of Ethics (Most Leading Authors are experts in this domain for ICT, in particular for E-service).

The Authors ensure that the work described has been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans, in conformity with the E-service domain rules.

All animal experiments should comply with the ARRIVE guidelines and should be carried out in accordance with the U.K. Animals (Scientific Procedures) Act, 1986 and associated guidelines, EU Directive 2010/63/EU for animal experiments, or the National Institutes of Health guide for the care and use of Laboratory animals (NIH Publications No. 8023, revised 1978) and the authors should clearly indicate in the manuscript that such guidelines have been followed. This follows from the fact that E-service does need really human behavior from the CCS (Computer Control System) designers and implementers interested in the real E-service work.
