A sender-side process directed to processing an electronic message destined for a recipient, comprising solving a computational problem involving at least a portion of the message, thereby to produce a solution to the problem. Optionally, a degree of effort associated with solving the problem may be assessed and the message is further processed in accordance with the assessed degree of effort. Further processing refers to determining whether the degree of effort was within a range set by the sender or the recipient and if not, the computational problem is adjusted and solved again. The message is then transmitted to a recipient, who is informed of both the solution to the problem and the problem itself. The recipient executes a recipient-side process, which includes, upon receipt of the message: assessing the degree of effort associated with generation of the message using its knowledge of the problem and the solution; and further processing the message in accordance with the assessed degree of effort. High and low degrees of effort, respectively, will point to electronic messages having high and low legitimacy, respectively.
