Chinese Wall

A Chinese wall or ethical wall is an information barrier protocol within an organization designed to prevent exchange of information or communication that could lead to conflicts of interest. For example, a Chinese wall may be established to separate people who make investments from those who are privy to confidential information that could improperly influence the investment decisions. Firms are generally required by law to safeguard insider information and ensure that improper trading does not occur. The term is used in journalism to describe the separation between the editorial and advertising arms.[17] The Chinese wall is regarded as breached for "advertorial" projects.[18] Separately, the term can refer to a separation between a publication's news and opinions arms. https://en.m.wikipedia.org/wiki/Chinese_wall
