Can patented technology be kept secret?

Patents are obtained through public means in exchange for monopoly rights. Without publicity, there is no patent right. Therefore, confidentiality and patent rights cannot be shared, unless some technical parameters or key points are deliberately hidden in the submitted technical scheme, but this cannot completely protect your technology, that is to say, it is difficult to investigate the responsibility if those key technical points are leaked, because they are not listed in your patent claim. Anyway, this matter has advantages and disadvantages, depending on how you choose your own needs.
