تعداد بازدید : ۱۱۸۵ تعداد دانلود : ۵۱۷
در جهان مجازی دارایی مجازی به صورت کدهای نرم افزاری خاصی تعریف می شود که مانند اشیاء فیزیکی، دارایی های شخصی جهان واقعی و یا بخشی از واقعیت عمل کرده و دارای کیفیات مشابهی هستند. دارایی های مجازی به جهت بهره مندی از حمایت قانونی باید چندین شرط را برآورده کنند. این دارایی ها نه تنها باید خصوصیات فیزیکی دارایی های جهان واقعی را داشته باشند، بلکه باید دیگر خصوصیات نامحسوسی که قابل تفکیک از دارایی های واقعی نیستند را هم دارا باشند. ابهامی که درمورد مفهوم دارایی مجازی وجود دارد بسیار شبیه به ابهامی است که در مورد مفهوم دارایی واقعی وجود دارد. از آن جایی که کلمه دارایی درحقوق واقتصاد درمعانی متفاوتی به کار می رود چنین ابهامی دور از انتظار نیست. عوام دارایی را به صورت مالکیت اشیاء وچیزها می بینند. حقوقدانان دارایی را به صورت حقوق مرتبط با اشیاء و مسائل تعریف می کنند. علاوه بر تفسیرهای متفاوتی که از مفهوم دارایی وجود دارد، مسئله این است که قانون جهان واقعی بر دارایی های محسوس (به جز چند مورد استثناء) تاکید می کند که این مسئله در سیستم های حقوقی رومی – ژرمنی بسیار بارز است. به دلیل تمرکز بر خصوصیت محسوس بودن دارایی ها به نظر می رسد که حقوقدانان بحث دارایی های مجازی را کاملاً مورد بی توجهی قرار داده اند. به هر روی، شرط محسوس بودن دارایی ها تنها دلیل این بی توجهی نیست، موارد استثنایی وجود دارند و امکان توسعه بحث دارایی های مجازی موردی است که در سالهای اخیر بسیار مورد توجه بوده است. در این مقاله به شیوه توصیفی تحلیلی به تبیین این مقوله اشاره داشته ایم.
