halvmask

Halvmask is a term used in several contexts to denote a mask that covers only part of a form, most commonly the upper or lower half of the face. The word blends halv(e)/half with mask and appears in Scandinavian languages as a general label for partial masks. In cultural and theatrical settings, halvmask refers to half-masks worn for disguise or decorative purposes. A well-known example is the Colombina-style mask used in Commedia dell'arte and Venetian carnival traditions; these masks typically cover the eye area and upper cheeks, leaving the mouth exposed, and are commonly made of papier-mâché, leather, or lightweight resin, often decorated with paint, glitter, or feathers and secured with ribbons or pins.

In information security and data privacy, the idea of masking part of a value is sometimes described as a halvmask, though the terminology is not standardized. Such partial masking hides enough data to protect privacy while preserving usable context, as in showing only the last four digits of a credit card number or obscuring middle characters of identifying strings.

Other uses of the term may appear in fashion, design, or imaging, where a half-face silhouette or a partial overlay is employed. See also half mask, masking, and Colombina.
