The focus of this work is the legal expression of the copyright owner's personal right to maintain the integrity of his work in Germany and the USA. The law must provide the necessary protection against adaptation especially in this age of ever simpler and faster adaption technology, which serves to customize work to meet user needs. It is vital to have legal protection not only because of the copyright owner's interest in the integrity of his work but also based on the user's interest in the authenticity of the work. Integrity protection is most influenced by political and economic decisions, which walk a fine line between the profit oriented work valuation and personality protection.
